Help us shape the future of the Biodiversity Heritage Library

The Biodiversity Heritage Library (BHL) is at a turning point. After nearly two decades of calling the Smithsonian Institution home, BHL must transition to a new hosting structure beginning in January 2026. Since receiving that news, we’ve been working steadily to secure a strong and sustainable future for BHL. In our last update, we shared the appointment of a Transition Director, the formation of a Transition Team, and a partnership with a fiscal sponsor.

Today, we release our official Call for Support. This is a pivotal moment in BHL’s journey, and we are counting on our community to help spread the word and contribute in whatever ways you can. BHL’s enduring strength comes from its international consortium and diverse community of scientists and citizen scientists who use the platform to explore, understand, and protect biodiversity. Support comes in many forms–some visible, some behind the scenes–but all are vital to BHL’s future.

Additionally, in keeping with our commitment to transparency, we are updating our Frequently Asked Questions (FAQs) to include information about the transition. New questions will be added regularly, so we encourage you to read and visit them often.

Stay tuned for our next Transition Update, here on the BHL blog.

Leadership, Fiscal Sponsorship, and Hosting Opportunities

In April 2025, the Biodiversity Heritage Library (BHL) released a public statement announcing that the Smithsonian Institution, our administrative and technical host since 2006, will step back from this role as of January 1, 2026. That announcement marked the beginning of a new chapter for BHL: one filled with both challenges and possibilities.

Today, we’re pleased to share the first in a series of monthly blog posts that will provide open updates on the progress of our transition. We know uncertainty can be unsettling, and we want to assure our global users, partners, and supporters that the transition is well underway, and that we are actively building a stronger and more sustainable future for BHL.

Strong Leadership: Welcoming Our New Transition Director and Communications Director

Kelli Trei, BHL Transition Director

We are delighted to announce that Kelli Trei has been appointed as BHL’s Transition Director. Kelli, Biosciences Librarian and Associate Professor from the University of Illinois Urbana-Champaign, brings a wealth of leadership experience and a deep commitment to BHL. Most recently, she has served as Vice-Chair on the BHL Executive Committee and the EC Secretary before this. Her leadership, steady presence, and long-standing engagement with BHL have proven invaluable during early transition planning.

Nicole Kearney, BHL Communications Director

We are also pleased to share that Nicole Kearney, Manager of BHL Australia and Chair of BHL’s Persistent Identifier Working Group, has been appointed as BHL’s Communications Director. Nicole brings over a decade of experience with BHL and a strong record of international collaboration, digital engagement, and strategic communication. As Communications Director, she will lead BHL’s internal and external communications through the transition and into the next chapter.

Kelli, supported by Nicole, is leading a dedicated Transition Team composed of members of the BHL Executive Committee and the BHL Secretariat.

A New Foundation: Fiscal Sponsorship

We are also pleased to share that BHL members have voted to enter into a fiscal sponsorship agreement with an established U.S.-based 501(c)(3) organization. Under this partnership, the fiscal sponsor will provide essential nonprofit administrative services, including contracting and HR, while BHL will retain control over staff supervision, strategic priorities, and community direction.

This marks a critical turning point. For the first time, BHL will be able to operate with financial autonomy, fully aligned with our global mission, partners, and community.

Coming Soon: Call for Hosting Partners

Although BHL will be able to begin its fundraising push in the near future under its forthcoming fiscal sponsorship, our essential work continues – and so does our need for support. Securing a new fiscal home is an important milestone, but we are still working to safeguard our critical secretariat roles, who carry out the vital operational and technical functions for the global BHL community. In order for this work to continue beyond January 1, 2026, we need your help.

In the coming weeks, we will release a formal Call for Support of the core operational and technical functions of BHL. While we would welcome a single organization taking on the hosting of BHL, the secretariat’s separate but connected roles could also be hosted by different organizations. We are thus open to a distributed hosting model where key functions of BHL may be supported by different institutions. We encourage potential hosting organizations to think outside the box.

Institutions interested in supporting BHL’s next chapter – by hosting roles, staff, infrastructure, or services – are encouraged to respond to this call. We are excited to explore new partnerships and welcome new champions into our network.

Transparency Throughout the Transition

We are committed to regular communication during this transition. These blog posts are just one part of that commitment. In the months ahead, we’ll continue to share updates, answer questions, and invite feedback from our global community.

From April 7–11, 2025, the global Biodiversity Heritage Library (BHL) community gathered at the Museum für Naturkunde in Berlin for the BHL Annual Meeting. Hosted at one of Europe’s premier natural history museums, this year’s event brought together BHL Members, Affiliates and stakeholders for a week of strategic planning and collaboration.

Attendees of the BHL Annual Meeting gathered outside the Museum für Naturkunde.

Navigating Transition Amidst Change

BHL Annual Meetings are usually a time for joyous reunions and celebration of shared successes. This year, however, the meeting was shadowed by the recent announcement that BHL must secure alternative funding and find a new institutional host. In the weeks leading up to the Annual Meeting, the original agenda pivoted swiftly towards solution-building. While core elements like committee reports and the ever-popular #BHLDay remained, much of the program was reshaped to focus on navigating the transition.

A Week of Engagement and Collaboration

The week began with a guided tour of the Staatsbibliothek zu Berlin‘s digitization center and rare manuscripts collection. A highlight for many was a sneak peak of the Library’s digitisation and animation of 3D pop-up books, a beautiful illustration of blending heritage with technology. Following the tour, attendees gathered at Restaurant Ursprung (beneath the fabulous Dussmann KulturKaufhaus bookshop) to reconnect and share updates over local cuisine.

Business Meetings and Strategic Planning

Formal business meetings commenced on April 8, with BHL Chair David Iggulden welcoming both in-person and virtual participants. Reports from the Chair, Program Manager, Collections Manager, Data Manager and Technical Team highlighted BHL’s progress over the past year, while discussions around strategic restructuring and sustainability set the foundation for critical transition planning. This was followed by updates from the Chairs of BHL’s various committees and working groups. Participants also engaged in workshops exploring how to future-proof BHL’s data infrastructure and navigate the technical scenarios involved in the upcoming shift from Smithsonian hosting.

Between meetings, attendees were treated to behind-the-scenes tours of the Museum für Naturkunde’s Library, Archives and Taxonomy Workshop. While all the tours were fabulous, we were especially wowed by the passion and exceptional work of the Museum für Naturkunde’s taxidermists. It was abundantly clear why Museum für Naturkunde wins so many taxidermy championships!

Democratizing Knowledge at the Swiss Embassy

One of the week’s standout events was the evening panel and reception at the Swiss Embassy, titled Democratizing Knowledge: The Role of Open Data in the Age of AI. The panel emphasized the critical importance of open access in a rapidly evolving technological landscape. BHL Program Manager Colleen Funkhouser and BHL Executive Committee Co-Secretary Elisa Herrmann (our host in Berlin) spoke as part of the expert panel, contributing to an important discussion on the global impacts of biodiversity data.

BHL Day 2025: Bridging Data and Nature

On April 9, the Museum für Naturkunde opened its doors for BHL Day 2025, a public symposium themed Bridging Data and Nature: Connecting Information, Technology, and Biodiversity. The event featured a lineup of speakers exploring how technology and open-access initiatives are transforming biodiversity research. Topics included data interoperability for enhanced global research collaboration, linked open data for connecting taxonomic literature with modern biodiversity platforms, and the role of digitized literature in supporting conservation efforts. A recording of the event is now available on the BHL YouTube channel.

The symposium concluded with an evening reception in the Museum’s spectacular central atrium, surrounded by towering dinosaur skeletons and one of the world’s most famous fossils, Archaeopteryx lithographica. The breathtaking setting provided a fitting backdrop to reflect on BHL’s mission to preserve and democratize access to the world’s biodiversity literature.

Strategic Planning for a Sustainable Future

The final business meetings on April 10 focused heavily on stakeholder engagement, future funding models, and transition planning. Members and Affiliates discussed potential hosting scenarios and laid the groundwork for BHL’s Secretariat transition. Critical work began on drafting transition documents and communications, including the Public Statement announcing BHL’s need to transition from the Smithsonian, which was released the following week. The meeting concluded with a heartfelt recognition of partners and a special thanks to Elisa Herrmann and the Museum für Naturkunde for their wonderful hosting of this year’s event. As we closed, our fabulous hosts had one final surprise for us: “BHL Annual Meeting 2025 Berlin” spelled out in traditional Berliner donuts!

Looking Ahead

As BHL advances towards its next chapter, the 2025 Annual Meeting served as a powerful reminder of our community’s collective commitment to open access, global collaboration, and the preservation of biodiversity literature. With transition planning now well underway, BHL is relying on its community and partners to shape a sustainable and resilient future. We look forward to continuing this momentum in the months ahead, supported by the strength of our community and the critical partnerships that make BHL’s mission possible.

BHL’s future is hopeful, but uncertain. BHL is committed to transparency during the transition. We will be sharing monthly updates here to keep our community informed. Subscribe to this blog to stay up to date. In the meantime:

If you have landed on this page expecting to find an article published in the Journal of Research on the Lepidoptera from 2018-2022, you’re in the right place. Read on…

R.I.P Journal of Research on the Lepidoptera

In 2017, The Journal of Research on the Lepidoptera published its final issue. The journal’s website was turned off and, to ensure ongoing access to the biodiversity knowledge contained within its articles, all volumes (1-49) were made freely available on BHL. The final editorial, entitled “JRL R.I.P.” was written by Rudolf H. T. Mattoni, the then President of the Lepidoptera Research Foundation. You can find it on BHL here.

Volume 49, the final issue. Cover. The Journal of Research on the Lepidoptera. 2017. Contributed in BHL by Smithsonian Libraries. Rights Holder: The Lepidoptera Research Foundation, Inc.

Pirate publishers

Jump forward five years. On 4 January 2022, Scott Miller (@PNGmoths) tweeted about the sad passing of his friend Rudolf H. T. Mattoni (1927-2022). Miller’s tweet prompted the realisation (by Roderic Page) that a “bad actor” had resurrected the Journal of Research on the Lepidoptera website and had been using the journal’s title and ISSN to publish new articles. From 2018 onward, the fraudulent party published 262 articles in six issues across two volumes. These articles were not about lepidoptera (butterflies and moths); they covered a seemingly random array of topics, including economics, health, and business management.

The “current issue” (volume 50) of The Journal of Research on the Lepidoptera published in 2019 on the resurrected JRL website.

ISSN hijacking & fraudulent DOI assignment

Each article published in the Journal of Research on the Lepidoptera after 2017 sits behind a paywall on the resurrected website and has been assigned a DOI (a digital object identifier). This means that the pirate publisher must have applied to Crossref (the DOI registration agency for scholarly content) and established themselves as the “owner” of the journal’s ISSN. This was possible because no other party had ever assigned a DOI to any component of the journal and, as the pirate publishers were masquerading as the Lepidoptera Research Foundation via the resurrected original website, no flags were raised (although Crossref did revoked their membership in April 2021 for non-payment of fees).

Rod Page’s announcement spurred a flurry of tweets and emails between the original (rather cross) editors, BHL’s Persistent Identifier Working Group (PIWG), Crossref and the ISSN Authority. The legitimate editors informed Crossref that BHL is the only party with their permission to host the journal and assign DOIs to the articles. However, Crossref’s transfer of ownership policy required BHL to submit an official title dispute. The “owning” member was then notified of the dispute and given 10 working days to respond. When they did not respond, Crossref transferred ownership of the Journal of Research on the Lepidoptera to BHL.

BHL DOIs for the real Journal of Research on the Lepidoptera articles

In May 2022, BHL’s PIWG, who have been retrospectively assigning DOIs (#RetroPIDs) to articles on BHL since 2020, assigned a DOI to every article published in the Journal of Research on the Lepidoptera up to its official final volume (1962-2017). Now that they have DOIs, these articles are part of the modern linked network of scholarly research. Every article can be persistently cited by modern researchers, those citations can be tracked, and the new DOIs will provide citation metrics for the articles’ authors and their institutions.

The first article of the first volume of The Journal of Research on the Lepidoptera. This 1962 article now has a DOI: https://doi.org/10.5962/p.333405. Page 3. Journal of Research on the Lepidoptera. 1(1):3-20, 1962. Contributed in BHL by Smithsonian Libraries. Rights Holder: The Lepidoptera Research Foundation, Inc.

Illegitimate URL persistence (despite our efforts)

Our early investigations into the resurrected website lepidopteraresearchfoundation.org established that the domain had been re-registered with a web hosting provider. Further digging uncovered that it had also been registered by a private proxy registration service that guarantees to “protect your identity”. Though we requested that these providers take down the website, there were limited options. Domain registries and web hosting services have specific terms of service and legal boundaries that limit their access to and jurisdiction over the content on the sites they host.

At the time of writing (September 2022), the pirate publishers remain unidentified and the website lepidopteraresearchfoundation.org persists. However, for the time being, only the home page of the Lepidoptera Research Foundation is accessible; attempts to access any other page of the website results in a 403 error.

A tombstone for the fraudulent articles

BHL then had to decide what to do with the 262 DOIs assigned to the fraudulently published articles, which, as the new owner of the ISSN with Crossref’s system, BHL now has responsibility for (and control of). Unfortunately, we couldn’t undo their existence; as persistent identifiers, DOIs must persist. After consultation with the true editors, it was decided that the fraudulently assigned DOIs should point here: to an explanation of why they shouldn’t exist.

This makes this blog post the tombstone page for all those articles – the final resting place of their immortal, yet retired, DOIs. A tombstone page is a special type of landing page that a DOI can point to when its content has been removed, such as in cases of research retraction. Tombstone pages, like all landing pages for DOIs, should contain a full bibliographic citation (so users know they’ve been directed to the correct place). Tombstone pages should also include a statement of unavailability explaining why the content is no longer available. We hope this blog post serves as this statement. The DOIs and their metadata are listed below.

To all the authors who published in the two most recent volumes of the Journal of Research on the Lepidoptera, we hope you find somewhere more appropriate to republish your non-lepidopteran research (only three of the 262 articles published in the resurrected journal are about lepidoptera).

In October 2020, BHL launched a new working group with a momentous goal: to make the content on BHL persistently discoverable, citable and trackable using DOIs (Digital Object Identifiers).

The members of BHL’s new Persistent Identifier Working Group (PIWG).

A DOI is like an electronic fingerprint in the form of a unique and permanent alphanumeric string that provides a persistent link to a piece of content online. Modern publications receive a DOI at the point of publication. This DOI becomes a key part of a publication’s bibliographic metadata that should be included in any mention or citation of that publication. Reference lists in modern publications are filled with DOIs, which allows readers to click from publication to publication in (in theory) a never-ending chain of knowledge.

This reciprocal linking of DOIs has created a great linked network of scholarly research, but that network is missing the historic literature. The vast majority of historic publications lack DOIs. This means they appear in reference lists as unlinked citations. In our increasingly online world, readers are far more likely to read (and thus cite) publications they can click through to (particularly when libraries are inaccessible during a global pandemic). The upshot of this is that the millions of pages of historic literature on BHL—the foundation of our understanding of biodiversity—is in danger of falling into obscurity.

BHL has been retrospectively minting DOIs for historic publications since 2011, but the focus has primarily been on monographs. BHL’s new Persistent Identifier Working Group (PIWG) is (at least initially) focusing on journal articles. Minting DOIs for articles on BHL is a far more complex and time-consuming task than minting DOIs for monographs. This is because article DOIs need article data: every journal volume uploaded onto BHL must be accompanied by journal and volume data, but there is no requirement that contributors provide article data.

Thankfully, there have been considerable efforts to add article data to BHL (and thereby make it possible to search for the titles and authors of these articles both within BHL and via external engines). A huge proportion of this article data has been contributed to BHL by Roderic Page via BioStor: 75% of the 300,753 articles indexed in BHL as of 4 May 2021 were “defined” by BioStor. It is very difficult to determine how many articles are actually on BHL (hidden within all those journal volumes). But, while we don’t know what proportion of BHL’s journal content still needs to be made discoverable, we know there is still a huge amount of work to do.

COVID-19 provided an unexpected opportunity to make a considerable dent in this work. With no access to scanners or library materials, a number of BHL contributors, including Harvard University Libraries, Muséum National d’Histoire Naturelle and BHL Australia, pivoted from making new content accessible to making their existing content on BHL more discoverable. For example, BHL Australia’s digitisation volunteers gathered, gap filled and checked article-level metadata for over 30,000 articles in 2020.

Once an article has been defined, i.e. it exists as a publication unit in BHL and has its own article landing page (and we’ve checked that the article does not already have a DOI), we can assign a DOI to it. Articles that have recently been assigned BHL DOIs include some very old publications, such as the first scientific description of the Duck-billed Platypus, published in 1799 (https://doi.org/10.5962/p.304567), and the species descriptions from A specimen of the botany of New Holland, the first publication dedicated to Australian flora (1793-5), e.g. https://doi.org/10.5962/p.312432. The PIWG has also started assigning DOIs to in-copyright publications (with permission from the rights holders). These include articles from the Bulletin of the British Museum, e.g. https://doi.org/10.5962/p.310418, and the Bulletin of the African Bird Club, e.g. https://doi.org/10.5962/p.308885.

If an article on BHL has an existing non-BHL DOI, we add this key piece of bibliographic metadata to the BHL landing page for the article. This ensures that BHL users can link to the definitive version of the article (the one the DOI resolves to), and more importantly, that other parties (and their algorithms) can find our versions from elsewhere. This is particularly important when commercial websites lock their DOI’d versions of public domain articles behind paywalls. Having their DOIs on our freely accessible versions ensures that services like Unpaywall can find them. To learn more about how this works, see our blog post: BHL Journal Articles Are Now Discoverable via Unpaywall.

DOIs not only improve discoverability and enable persistent linking to our historic content; they also allow us to track how BHL content is being used. In the six months following the minting of its new DOI (Oct 2020 to April 2021), the 1799 Platypus description was tweeted by 219 Twitter accounts, referenced in six Wikipedia pages, picked up by one news outlet and cited in one academic paper (data from Altmetric, April 2021). We know this because the article has a DOI.

Altmetric’s overview of attention for the first scientific description of the Duck-billed Platypus (Shaw 1799): https://www.altmetric.com/details/91788579.

The PIWG has spent the past six months creating, refining and testing tools that will allow BHL contributors to do this work themselves. We have also been producing documentation that explains a) how to use the new tools, and b) why this work is so important. These tools will facilitate every step in the article discoverability and DOI assignment process including: downloading existing article data for a given journal title to allow for correction and gap-filling (in development); bulk uploading of article data for new articles (available now); and adding articles and titles to BHL’s (new) DOI Assignment Queue (available now). Our dream is that, whenever anyone uploads a journal volume to BHL, they also provide the data for the articles it contains (and thus take responsibility for making that content discoverable).

The Persistent Identifier Working Group (PIWG) is fueled by the technical expertise, metadata dexterity and incredible passion of:

• Nicole Kearney, Manager BHL Australia (Chair)
• Mike Lichtenberg, BHL Lead Developer
• Susan Lynch, Systems, Digitization & Web Services Librarian, The New York Botanical Garden
• Bess Missell, Metadata Librarian, Smithsonian Libraries and Archives
• Roderic Page, Professor of Taxonomy, University of Glasgow
• Joel Richard, BHL Technical Coordinator | Head of Web Services & IT, Smithsonian Libraries, Smithsonian Libraries and Archives
• Diane Rielinger, Digital Projects Librarian, Botany Libraries, Harvard University Herbaria
• Colleen Funkhouser, BHL Program Manager

The specific goals of the group are:

• To add article-level metadata to journal articles on BHL
• To add existing DOIs to (new and existing) article landing pages on BHL (particularly for those articles where the DOI’d version is behind a paywall elsewhere)
• To assign BHL DOIs to articles that lack DOIs

Ten years ago in June 2010, the Atlas of Living Australia and Museums Victoria signed an agreement with the Biodiversity Heritage Library – and BHL Australia was born.

BHL Australia’s mission is to make Australia’s biodiversity literature freely accessible and discoverable. Ten years ago, we started with a single contributing organisation, Museums Victoria, and a team of five incredibly dedicated volunteers.

Over the past 10 years, BHL Australia has grown considerably. Our operation is still hosted by Museums Victoria (at the Melbourne Museum), but we now digitise literature (and ingest born-digital material) on behalf of 27 organisations across the country.

We are now a truly national project, representing Australia’s state and territory museums, herbaria, royal societies and field naturalists clubs, as well as government agencies and natural history publishers. Together these organisations have contributed more than 350,000 pages from over 2,400 volumes.

These volumes include treasures such as George Shaw’s The Naturalist’s Miscellany (1789-1813), Helena Forde and Harriet Scott’s Australian lepidoptera and their transformations, drawn from the life (1890-1898) and John Gould’s A synopsis of the birds of Australia, and the adjacent Islands (1837).

BHL Australia has also uploaded an extensive list of journals onto BHL (they may not be as pretty, but they’re just as important). To peruse all 2,400+ volumes, see our full BHL Australia Collection.

The Naturalist’s Miscellany includes the first published scientific description and illustration of the Duck-billed Platypus (Ornithorhynchus anatinus). Shaw, George. The Naturalist’s Miscellany. Volume 10. 1799. Contributed to  BHL by Museums Victoria. DOI: https://doi.org/10.5962/p.304567. 

Our volunteer team has also grown since 2010; BHL Australia now has 15 amazing volunteers who do the majority of our scanning, cropping, image processing and metadata addition work, as well as three science communication volunteers. (You may have seen their hugely successful takeover of the BHL Instagram account during #BirdWeek last year.)

Of course, like so many other digitisation operations around the globe, BHL Australia is now in lockdown (and has been since mid-March). But out of adversity comes opportunity. While in lockdown, we’ve switched our focus from physical to born-digital material. We’ve welcomed new contributors and have uploaded journal volumes published as recently as 2020. We’ve also started a major project (in collaboration with BHL superuser Rod Page) to upload article metadata for every Australian journal on BHL (we’re pretty obsessed with discoverability).

The Records of the Western Australian Museum is now complete on BHL from 1910 to 2019 as a result of our efforts (during our COVID-19 lockdown) to upload born-digital material from Australia’s journals.

And, like so many others, we’ve also had to postpone our celebrations. We had planned to invite all our Australian contributors and volunteers to a big BHL birthday bash. That’s on hold for now, but in the meantime, here are our BHL staff — Cerise, Chris, Veronica and myself — waving our thanks to all those who support BHL Australia. To our volunteers, our contributors, the Atlas of Living Australia and our BHL community around the world — thank you for a wonderful 10 years!

Earlier this week, Rod Page and I received an email from Richard Orr, the Lead Developer at Unpaywall, telling us that he had created a work-around that would finally enable the Unpaywall extension to discover content in BHL. And I (Nicole) literally spent the rest of the day jumping for joy. 

Let us explain: 

Firstly, what’s a DOI?

DOIs (Digital Object Identifiers) are used throughout the scholarly research community to uniquely identify academic articles. They help readers locate the definitive version of a published article, and they make linking together the academic literature much easier – look at any recent paper and you’ll see that most of the references cited have DOIs.

DOIs do two things: 1) they uniquely identify an article, and 2) they point to the online location of the definitive version of that article (typically hosted by the article’s publisher). 

Many articles are not free to read: a significant proportion of both recently-published and historic articles are locked behind paywalls. However, with the rise of open access, it’s increasingly the case that there may be a free version of an article available somewhere online. BHL, for example, has scanned and made available tens of thousands of articles that also exist on commercial publishers’ websites. DOIs always direct users to the definitive version of an article. But if the definitive version is behind a paywall (as they so often are), how do we tell users that BHL has a free version available? Enter Unpaywall.

What’s Unpaywall?

Unpaywall finds (legally) open access versions of paywalled literature. Since its launch in 2016, Unpaywall has become an indispensable tool for scientists  (see “How Unpaywall is transforming open science”). Unpaywall’s free browser extension (downloadable via their website) displays a discrete padlock symbol on the side of your browser whenever you are on a paywalled paper. If Unpaywall is able to locate a freely-accessible copy of the article elsewhere, the padlock symbol appears green and clicking on it will take you directly to the open access version. To discover whether an article is free, Unpaywall scans a database of millions of articles compiled from over 50,000 sources. Until this week, BHL wasn’t one of them. 

Why couldn’t Unpaywall link to BHL?

BHL contains hundreds of thousands of journal articles. More than a quarter of a million of these articles have been indexed (the vast majority by Rod Page via Biostor), which means that they now have article-level landing pages containing their article-level metadata. Tens of thousands of these article landing pages now have DOIs. This should have made them discoverable, but Unpaywall still couldn’t find them. 

In June, we contacted Unpaywall to find out why. It turns out that the reason BHL content has never been picked up by Unpaywall is because of the way BHL uploads and presents its journal content. Most providers of online journals present each article neatly packaged as an individual PDF. BHL, however, is first and foremost a virtual library. We upload complete volumes of journals made up of individual page images. Our article landing pages don’t link to PDFs; they link to the page in the volume upon which the article starts. Unpaywall looks for a PDF link to confirm that the document is actually available. Thus, the 57 million pages of open access content on BHL was excluded from Unpaywall’s database.  

After we explained to Unpaywall how significant BHL’s content was, Richard Orr, Unpaywall’s Lead Developer, very kindly agreed to create a work-around, specifically for BHL, that would enable Unpaywall to link to BHL article landing pages. The result of this work-around is that (as of this week) 43,000 journal articles on the BHL website are now discoverable via Unpaywall. 

To demonstrate how useful this is, here are two examples:

The first description of the iconic (sadly now-extinct) Thylacine (or Tasmanian Tiger) was published in the Transactions of the Linnean Society of London in 1808. This article is well and truly out of copyright and yet the definitive version of this article is behind a paywall on the Wiley Online website: https://doi.org/10.1111/j.1096-3642.1818.tb00336.x. Downloading the PDF of this out-of-copyright article from the Wiley website will cost you $42 USD.

The definitive DOI version of this article is behind a paywall on the Wiley Online website, but it is freely available on the BHL website. With the Unpaywall extension, you can now easily navigate to the free version on BHL.

Now that BHL’s content is discoverable via Unpaywall, anyone directed to the Wiley version via the article’s DOI can discover the free version on BHL (via the Unpaywall extension).

Article freely available via the Biodiversity Heritage Library.

It’s important to note that making BHL discoverable via Unpaywall doesn’t just enhance access to legacy literature such as the Thylacine paper; it also applies to much more recent research. For example, “The generic relationships of the new endemic Australian ant spider genus Notasteron (Araneae, Zodariidae)” was published in The Journal of Arachnology in 2005. This article has the DOI (https://doi.org/10.1636/04-56.1) and is behind a paywall on BioOne. With Unpaywall’s extension in your browser you can now discover the free version hosted by BHL.

How to make even more BHL content discoverable via Unpaywall

43,000 may seem like a large number, but it’s actually only a tiny fraction of the articles freely available on BHL. For the Unpaywall extension to be able to locate all the journal content on BHL, we need to unlock the rest of the journal articles on BHL by 1) adding more article-level metadata, and 2) ensuring that, for every article on BHL that has an existing DOI, we include that DOI in the article-level metadata. That’s our next task…

We would like to thank Unpaywall for providing access to an ever-increasing number of open access scholarly articles (23,943,966 at 14/8/19) and to particularly thank their Lead Developer, Richard Orr, for making it possible for BHL (a square peg) to fit into their open database (a round hole).
