The collected works of Stieltjes and Brouwer have been published with support from KWG.

Together with the Dutch Society for Mathematics Teachers, NVvW, KWG has founded Stichting Epsilon in 2005. The goal of this foundation is safeguarding the activities of Epsilon Uitgaven, i.e., the publication of their series of mathematics texts  and the Zebra series .

Between 1906 and 1960, KWG has published the series Wiskundige Opgaven met de oplossingen, mathematical problems and their solutions.
