Welcome to the Biodiversity Heritage Library Blog

At first glance one notices the unusual oblong-shaped book at 9” x 7” x 3” in a deep brown leather binding.

Peeking inside, there are pages and pages of botanical woodcuts – more than 1,020 – each with at least two woodcuts per leaf. For our purposes, a woodcut is an illustration engraved into a block of wood.

What is this copiously-illustrated work?

Eicones plantarum seu stirpium, arborum nempe, fructicum, herbarum, fructuum, lignorum, radicum, omnis generis : tam inquilinorum, quàm exoticorum : quæ partim Germania sponte producit, partim ab exteris regionibus allata in Germania plantantur : in gratiam medicinæ reiâque herbariæ studiosorum, in tres partes digestæ : adiecto indice gemino locupletissimo [Francofurti ad Moenum: Nicolao Bassaeo, 1590], by Iacobus  Theodorus (1522 or 1525 – 1590).

Or, using an abridged, summarized, and modernized translated title, “Pictures of plants, trees, herbs, fruits, and roots that are native to Germany and foreign countries, which are used for medicinal purposes, for apothecary students, and divided into three parts with the addition of a double index”.

On 25 August – 1 September 2018, BHL representatives from around the world traveled to Dunedin, New Zealand to attend the joint Society for the Preservation of Natural History Collections (SPNHC) and Biodiversity Information Standards (TDWG) conference. Hosted by the Otago Museum and the University of Otago, the conference represented several firsts, including the first joint meeting of these two organizations plus the first SPNHC meeting in the Southern Hemisphere.

With the theme “Collections and Data in an Uncertain World”, the conference was an opportunity for bioinformatics and natural science collections professionals to exchange ideas and expertise as they explored the myriad intersections between collections and the data generated from them. BHL, an institutional member of TDWG, was proud to be a conference partner for this important event.

As I am wrapping up a short 10-week virtual internship with the Biodiversity Heritage Library, I believe that I will look back on this experience as one of those pivotal opportunities that impact the course of life.

The internship was made possible by the LIS Education and Data Science for the National Digital Platform (LEADS-4-NDP) fellowship program through Drexel University and funded by the Institute of Museum and Library Services, in collaboration with BHL. LEADS-4-NDP has a mission to improve library services by providing LIS (Library and Information Science) educators and researchers with data science skills.

BHL offered an ideal data science challenge for a future LIS scholar like me to explore: a huge dataset of documents spanning five centuries, along with an engaged community of users and researchers interested in extracting new knowledge from these fascinating texts!

We’re excited to announce the launch of the new About BHL site!

What is BHL’s history? Who’s involved in the Library? What tools and services does BHL offer? How do you search, download content or access data and developer tools in BHL? How can you get involved in the Library? What projects has BHL engaged in?

Find the answers to these questions and much more information about the Biodiversity Heritage Library on our new About site at about.biodiversitylibrary.org!

The passenger pigeon’s demise is one of the most infamous examples of human-caused extinction. Once the most abundant bird species in North America, it was hunted relentlessly, with large-scale commercial hunting facilitated by railroad distribution placing excessive pressure on the species. The population declined from billions to none in less than one hundred years.

The last passenger pigeon, Martha, died at the Cincinnati Zoological Garden at about 1pm on September 1, 1914.

While stories of passenger pigeon flocks blackening the skies underscore the species’ once staggering abundance, its distribution was concentrated in the eastern United States. But could there have been resident populations in the western U.S.?

Passenger pigeon bones uncovered from the La Brea Tar Pits in Los Angeles, California inspired Dr. Libby Ellwood to ask this very question and embark on a research project empowered by the Biodiversity Heritage Library’s collections.

As part of BHL’s mission to ‘improve research methodology by making biodiversity literature openly available to the world as part of a global biodiversity community’, the BHL Secretariat and Partners regularly participate in meetings and initiatives centered on collaborating with other biodiversity organizations throughout the world. One such recent event was the 2nd Global Biodiversity Informatics Conference (GBIC2) held in Copenhagen from 24-27 July 2018.

Organized by the Global Biodiversity Information Facility (GBIF), the meeting convened stakeholders from across the biodiversity informatics community to explore a model for coordinating across geographic and political boundaries to share and link data managed by various biodiversity infrastructures. GBIC2 was organized to build on outcomes and recommendations from the first GBIC meeting held in 2012. The Global Biodiversity Informatics Outlook (GBIO) framework (pictured below), developed as part of that first GBIC meeting, served as a foundation for exploring various considerations–from the cultural to the technological–involved in managing and sharing resources related to biodiversity data, evidence, and understanding.

Version 3 of the BHL API has been launched.

The development of a new API version was spurred by the recent introduction of full-text search to the BHL web site. In addition to the inclusion of full-text search, the entire API has been examined and updated. New methods have been added, existing methods have been modified, and many methods have been dropped entirely (or incorporated into other methods).
