In addition to around 600,000 volumes, prints and manuscripts, the state library also houses domestic and foreign journals.

The library, which was known as the "Hessische Landesbibliothek" from 1963 to 2011, was integrated into the RheinMain University of Applied Sciences in 2011 and now forms the "RheinMain University and State Library" together with the former University of Applied Sciences Library.

It continues to function as a universal academic library with a focus on regional literature, but also provides students with basic literature.
