Welcome to the Biodiversity Heritage Library Blog

On 1 January 2026, the Biodiversity Heritage Library officially entered a new chapter.

Since its founding in 2006, BHL has been hosted by the Smithsonian Institution. We are profoundly grateful for the administrative, staffing, and operational support provided for nearly two decades. However, in April 2025, BHL announced that the Smithsonian would no longer host BHL beyond the end of 2025. That announcement marked the beginning of a carefully planned transition that would help define a new independent future for BHL.

A wave of support is building behind BHL. As we advance through our transition from long-term hosting by the Smithsonian Institution to a new independent governance and hosting model, one message has become increasingly clear: our global community is stepping forward to strengthen and sustain the world’s largest open-access library of biodiversity literature.

In response to BHL’s Call for Support, we have received a range of commitments from institutions in multiple countries. These include significant institutional donations, major in-kind technical support and expertise, technical hosting, and new organisations joining the BHL Member Council. Today, we are delighted to announce the first of these new Members: the University of South Florida Libraries (USF).

On 1 January 2026, the Biodiversity Heritage Library (BHL) will take flight, becoming fully independent after nearly two decades hosted by the Smithsonian Institution. This transition marks an historic milestone for BHL and for the global biodiversity and open-science communities we serve. It also brings an urgent challenge: ensuring that the infrastructure, staffing, and partnerships that keep over 500 years of biodiversity knowledge open to the world remain secure and sustainable.

This month, members of the biodiversity community from across the globe gathered in Bogotá, Colombia, for two major meetings: the Global Biodiversity Information Facility (GBIF) Governing Board Meeting (19–20 October) and Living Data 2025 (21–24 October).

For the Biodiversity Heritage Library (BHL), these back-to-back events were a timely opportunity to share progress on the BHL Transition and to connect directly with the global community that relies on BHL every day.

The Biodiversity Heritage Library (BHL) is launching a new public fundraising campaign to help us navigate our transition to independence. This is our first major campaign since the announcement that the Smithsonian Institution can no longer host BHL beyond 2025. Your support now is more critical than ever to secure BHL’s future.

On August 31, we reached the soft-close of the Biodiversity Heritage Library’s Call for Support.

First and foremost, we want to thank everyone who has reached out with offers – large and small – and to all who shared our call across their networks. We’ve received some very promising proposals, and we’ll be reviewing these in detail over the coming weeks.

As we review these offers, we want to be clear about what will guide our decisions. Over the past month, the BHL community has agreed on a set of Guiding Principles for the Transition (2025–2026). These principles reflect our shared values and priorities, and will guide our decision-making as we shape BHL’s future.

We’re thrilled to share some exciting news: 🎉 The Biodiversity Heritage Library has a new fiscal sponsor – the Council on Library and Information Resources (CLIR)!

This is a major step forward in securing a sustainable future for BHL.

As many of you know, the Smithsonian Institution will conclude its hosting role at the end of 2025. Since this announcement, BHL has been working diligently behind the scenes to establish new homes for its core functions. With CLIR now on board as our fiscal sponsor, the legal and financial infrastructure for BHL are firmly in place.
