The survey characterized 73 biomolecular databases to understand their funding, usage, and sustainability. It found that 66% had funding for one year or less, with only 6.5% funded for over five years. Usage was highest for databases with unique users, with the most used database receiving over 60 million hits per month. The results will help the ELIXIR infrastructure plan support for biomolecular databases and ensure long-term access to biological data.
