The Study Center of Museum Batavialand provides access to a unique collection of archives, books, maps and newspapers about the Zuiderzee/IJsselmeer region and Flevoland. The collections, collected by the Zuiderzee Association (1886-1949) and the Foundation for Population Research in the drained Zuiderzee polders (1936-present), among others, predate the reclamation and are still growing thanks to historical and archaeological research.
