The Geopolitics of Metadata: Knowing Panama Through the Biodiversity Heritage Library

Read the full blog post

In the first part of this blog series, I explained a portion of the analyses I performed during my time as an intern for the Biodiversity Heritage Library (July-August 2021). These analyses revolved around metadata patterns in BHL’s collection that highlight shortcomings in terms of diversification in the Library’s catalogue. In that post, by focusing on comparative metadata and the case of BHL México, I argued that an outreach plan that included the establishment of global partnerships between BHL and institutions in the Global South was a solid strategy to diversify the Library’s collections. This same argument is sustained by the second portion of the analyses I performed during my internship and that I present here, which deal primarily with patterns of associations and representation in the subject lists of BHL’s materials and the specific case of Central America and Panama.

The goal of the second part of my internship was thus to identify semantic patterns in subject lists that highlight the diversification—or lack thereof—in materials about Latin American biodiversity contained in BHL.

Understanding BHL Through Metadata: Patterns of Bio-Diverse Knowledge Production

Read the full blog post

During my time as an intern for the Biodiversity Heritage Library (July-August 2021), I worked on a project, I hope, will help engender important and critical conversations around the Library’s work and responsibilities vis-á-vis the sometimes harmful and problematic origins of its materials, as well as around the possibilities for the decolonization of its collection and archival practices. By focusing on the case of Latin America and her biodiversity, the main goal of this project was to identify patterns in the metadata of BHL’s collection that can inform decolonial policies and strategies for the diversification of the Library’s catalogue.

To identify such patterns, I extracted and analyzed the metadata of materials that include a subject related to Latin America in their subject lists. These analyses shed important light on diversification issues, specifically in the case of this region.

“BHL is a Game Changer for Scholars”: BHL Empowers Research on Landscape Gardening History

Read the full blog post

The large-leaved kōwhai (Sophora tetraptera) is native to the North Island of Aotearoa New Zealand, where it is widespread and common. While it grows naturally only in Aotearoa, it has been cultivated extensively outside of this range, including as one of a number of New Zealand plants historically introduced into English gardens.

Natural history literature provides a record of such introductions, with many authors remarking on the suitability of Sophora tetraptera—often referring to it under the synonym Edwardsia grandiflora—to the English climate. For example George Loddiges, within his The Botanical Cabinet(1826), remarked that it was “sufficiently hardy to bear our climate, planted against a wall; in very severe frost, a mat should be hung over it.” Two decades later, British writer and botanical authority Jane Wells Webb Loudon included the plant in herThe Ladies’ Flower-Garden of Ornamental Greenhouse Plants (1848), where she noted that the original plant could still be found growing in Chelsea Garden in 1848.

Loddiges’ and Loudon’s references are just two of many sources related to the history of Sophora tetraptera that Mark Laird (Professor, John H. Daniels Faculty of Architecture, Landscape, and Design, University of Toronto) identified thanks to the Biodiversity Heritage Library (BHL) whilst conducting research for a prospective book. One of the book’s chapters explores a variety of New Zealand plants introduced into English gardens from the 1770s to 1840s, in the context of both Kew’s colonial collecting and Māori heritage. BHL was an invaluable resource for this research—especially during the COVID-19 related lockdowns of 2020.

Backswimmers vs. Mosquitos: BHL Informs Research on Controlling Yellow Fever Mosquito Populations

Read the full blog post

Aedes aegypti, dubbed the yellow fever mosquito, is a globally invasive, pervasive threat to human health. As the common name suggests, the species can carry a range of diseases, including not only yellow fever but also dengue, the Zika virus, and the chikungunya virus. It is responsible for an estimated 400 million infections each year.

Chronicling the History of the Former Squires of Coulsdon: Rare Book Digitization Informs Research on the Byron Family

Read the full blog post

The Joseph F. Cullman 3rd Library of Natural History at the Smithsonian Libraries and Archives in Washington, D.C. is home to many rare and special books. Amongst the approximately 20,000 volumes in the library’s collection is a particularly rare item—one of only six known copies in public and institutional libraries worldwide.

The book is a privately printed journal by Edmund Byron entitled What we did in South Africa in 1873, which details Byron and his wife Charlotte’s 1873 exploratory and hunting expedition to South Africa. In 2015, at the request of a researcher, the Smithsonian digitized its copy of the journal and made it freely available online in the Biodiversity Heritage Library (BHL), where it was discovered by Dr. Nigel Elliott, who was conducting research on the Byron family.

This Bird Illustration Does Not Exist: Using Machine Learning and BHL Flickr Images to Produce “New” Bird Images

Read the full blog post

I work as a web developer for the agency Cogapp, which is based in Brighton, UK. We create websites and other digital services for museums, art galleries, archives and the like, but every couple of months we hold a “hack day”. A hack day involves spending a day working on projects which generally revolve around a particular theme and which ideally we can do in one day. This allows us to get the creative juices flowing and to further our agenda of innovation.

The theme this past hack day at Cogapp was ‘Museum APIs’, but the looser interpretation was that we were to use open data provided by museums in our projects. I was inspired by the Biodiversity Heritage Library’s Flickr which is a massive collection of free-to-use scientific images. I immediately knew I wanted to utilise this resource as I love scientific illustrations of nature.

I’ve also had an interest in Machine Learning for a while and I recently discovered Derrick Schultz and his YouTube channel Artificial Images. Here he publishes videos of his Machine Learning courses which he runs for people who want to use ML for creative purposes.

I watched Derrick’s tutorials on training a StyleGAN Neural Network and the things he was saying made a degree of sense to me, plus he had published a handy Google Colab notebook with step-by-step code, so I decided it was something I might be able to have a go at.

Hidden Biodiversity: Exploring Neotropical Fungus Weevils With the Help of BHL

Read the full blog post

In the last decades of the 19th century, a monumental publication on the biodiversity of Mexico and Central America began publication—Biologia Centrali-Americana. Published in 215 parts from 1879 to 1915 by the editors Frederick DuCane Godman and Osbert Salvin, the work describes over 50,000 species and is illustrated with over 1,600 lithographic plates depicting over 18,000 species. Remarkable for its time, the title is still vitally important for the study of Neotropical biodiversity today, as it contained virtually all known information at the time about Mexican and Central American flora and fauna.

Biologia Centrali-Americana is a particularly important resource for entomologist Samanta Orellana, a PhD student in evolutionary biology at the Dr. Nico Franz Lab of Arizona State University (ASU) and a research assistant in the ASU Biocollections of the Biodiversity Knowledge Integration Center. Orellana began studying insects and working with entomological collections more than a decade ago, during her undergraduate studies in her home country of Guatemala.

“For many insect groups in Guatemala and the rest of Central America, Biologia Centrali-Americana still represents the only source of information available for the region,” states Orellana.
