In the face of climate change and environmental challenges, understanding and documenting Earth's biodiversity is essential. The
Global Biodiversity Information Facility (GBIF) serves as a global repository for biodiversity data, playing a pivotal role in this critical mission of safeguarding our planet's biodiversity. Species occurrence data sourced from the Biodiversity Heritage Library (BHL) provides insights into species distributions, behaviors, and interactions much deeper into time, offering key species baseline data required to effectively address the climate crisis. Without accurate and comprehensive data in GBIF, our collective ability to track environmental changes and make informed decisions is severely hampered.
As a GBIF participant node, BHL is committed to sharing biodiversity data openly, adhering to FAIR (Findable, Accessible, Interoperable, Reusable) and CARE (Collective Benefit, Authority to Control, Responsibility, Ethics) data principles, and collaborating with a global network of biodiversity organizations to bolster and build capacity to strengthen the biodiversity information infrastructure. To honor our commitments, technical staff from BHL are working to establish a scalable data pipeline of occurrence data currently trapped in archival field notes, journals, letters, correspondence, and other primary source materials. The journey has been an arduous one due to poor OCR (optical character recognition) data quality for BHL’s sub-corpus of handwritten materials.
Originally scheduled for 2020, the BHL Annual Meeting finally made it to Paris after two years of virtual meetings and a break to hold the 2022 BHL Annual Meeting in conjunction with the Society for the Preservation of Natural History Collections (SPNHC) and the Natural Sciences Collections Society (NatSCA) meetings in Edinburgh, Scotland.
The host for the 2023 meeting was the library of the Muséum national d'Histoire naturelle (MNHN), led by Alice Lemaire, Clément Oury, and Gildas Illien. The meeting took place 17-21 April 2023 and included BHL business meetings, tours of library and museum sites, and a BHL symposium titled “Fostering Data Driven Natural Science through Open Digital Libraries”. In total, the meeting gathered 38 attendees (both in-person and virtually) from 22 BHL partners from around the world.

Auckland Museum joined the Biodiversity Heritage Library (BHL) in 2018 and currently remains the only organisation in Aotearoa New Zealand contributing to the consortium. During my four years working as a technician and coordinator on the project, and with the help of a volunteer, Brianna Vincent, we have added over 25,000 pages, increasing our library of contributions from three to over 100 biodiversity literature items. These items span from 1790 to 2004, covering over 200 years of biological knowledge, and range from field notebooks and sketches to identification guides, records and proceedings, educational textbooks, plant material, cyanotypes (blueprints), and hand-painted illustrations.
The Biodiversity Heritage Library is pleased to welcome two new Affiliates in 2023: Dumbarton Oaks in Washington, DC, and Meise Botanic Garden in Meise, Belgium. The BHL Consortium now includes 19 Members and 23 Affiliates.

In 2023, BHL's Technical Team dedicated significant efforts to improve our data ecosystem, now comprising 61+ million pages of biodiversity literature. Last year's Technical Priorities underscored BHL’s steadfast commitment to data quality by focusing on both upstream and downstream data flows. Notable milestones include delivering refined taxonomic data to researchers, implementing interface improvements based on user feedback, and forging data pipelines for existing and new downstream data consumers.
2023 proved to be a transformative year of growth, increased collaboration, and heightened dedication to advancing biodiversity knowledge for the BHL Cataloging and Metadata Committee. Last year, the Committee achieved significant milestones in committee governance, professional development opportunities, data quality updates, and the ratification of consortia-wide data policies, accompanied by comprehensive documentation.
William Ulate Rodríguez, past Biodiversity Heritage Library (BHL) Technical Director, died in St. Louis on September 20, 2023. William was a father, a friend, a colleague, and a passionate advocate of using the tools of bioinformatics to better understand life on our planet.
William's friends and colleagues share their fond memories of his life and work.
