The library is located in building A. It provides access to scientific literature, both journals and books, mainly online. The library collects and maintains data on the publishing activity of researchers and students affiliated with the Institute and coordinates the submission of catalog data to the Horizon Information Portal.

Library staff also perform bibliometric analyses and provide data about publications for the Polish Scholarly Bibliography system. The library participates in an interlibrary loan service, offering access to articles available from other scientific libraries and providing such access for other institutions. The library also runs and maintains a search tool which allows to browse articles and theses authored by researchers and students of IBB PAS (an index is available here).
