In 1737, Elizabeth Blackwell published the first weekly installment of a very ambitious project. The final work, entitled A Curious Herbal (1737-39), ultimately consisted of 500 plates of plants alongside 111 pages of text providing descriptions of their medicinal uses. Endorsed by the Royal College of Physicians, the publication helped satisfy the need for an up-to-date reference work for apothecaries.

A Curious Herbal is the subject of a chapter in Dr. Anna K. Sagal’s first monograph project, Resisting Gardens: Pedagogy and Natural Philosophy in Eighteenth-Century Women’s Work. By providing free, online access to relevant literature, such as Blackwell’s Herbal, the Biodiversity Heritage Library has been an important resource for Sagal’s research on the project.

Armed with rOpenSci’s packages binding powerful C++ libraries and open taxonomy data, how much information can we automatically extract from images? Maybe not much, but, experimenting with gorgeous drawings from a natural history collection, we can least explore image manipulation, optical character recognition (OCR), language detection, and taxonomic name resolution with rOpenSci’s packages.

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.
