For BHL’s content to be truly useful, individual articles need to be discoverable, citable, and connected to the wider scholarly record. Rod Page explores how BioStor has helped uncover more than 260,000 articles in BHL, the importance of article-level metadata and DOIs, and how AI may shape the future of article discovery.

The big day is here! BHL’s Tech Team is starting the three-week process of moving BHL’s technical infrastructure from the Smithsonian data center just outside of Washington, DC, to the Field Museum in Chicago, Illinois.

Pliny the Elder’s Natural History is one of the most influential works of the ancient world. This post explores BHL’s 1469 Venice edition, contributed by the Natural History Museum, London — a remarkable incunabulum and the oldest printed book in the BHL collection.

The Biodiversity Heritage Library continued our 20th anniversary celebration at our Annual Meeting in London from 27 April to 1 May. This year, founding members and 10th anniversary co-hosts, the Natural History Museum, London and the Royal Botanic Gardens, Kew, welcomed 46 representatives from 30 institutions across 8 countries to gather and plan for BHL’s future.

The Castlemaine Field Naturalists Club in Central Victoria, Australia, is celebrating its 50th year in 2026. Since its inception in March 1976, the Club has produced a monthly newsletter for members. All issues are available on the Club’s website and through the Biodiversity Heritage Library (BHL). Through BHL, they are fully searchable, meaning that species names, locations, and historical observations can be discovered by researchers anywhere in the world. This ensures that local knowledge contributes to a global, interconnected biodiversity resource.

One of the most vibrant and colourful volumes available on BHL from the Museums Victoria Archives is the Economic Botany Fruit and Vegetable Specimen Register (ITM Register) created by Industrial and Technological Museum (ITM) model makers and used as a reference when producing the Wax Fruit Collection. This collection dates from when the ITM (now Museums Victoria) opened to the public in 1870.

Reflections on Digitizing Medieval Medical and Botanical History

Last summer, as the Archival Systems Intern for the LuEsther T. Mertz Library of the New York Botanical Garden, I had the privilege of uploading several unique new items to the Biodiversity Heritage Library. Among them was one of the earliest Western medical manuscripts, a medieval pharmacopeia known as the Circa Instans. This manuscript, digitized from the New York Botanical Garden’s physical collections, was written in approximately 1190, making it the oldest item in the BHL’s collection. Although I did not know that it would become the BHL’s oldest item when I added it to the library, I nevertheless found myself marveling at the Circa Instans and the history of this particular manuscript.
