The Rotterdamsch Leeskabinet is an association which was founded on 17 March 1859. Formally, the objective of the association is: to preserve the collection of the Rotterdamsch Leeskabinet and organise activities in the field of culture and science.

In practice, this means that the association is responsible for managing and expanding a high-quality book collection which is part of Rotterdam's cultural heritage. The association also organises lectures and excursions on literature, history, science and more.

For over 150 years, the Rotterdamsch Leeskabinet Association has thus played an important role in the dissemination of knowledge from the fields of culture and science.
