Over the years, five catalogues of this Book Office have been published and the latter dates back to 1907. This is compiled by G. Mannoury and contains, in addition to an overview of the books and magazines that belonged to the WG then, an overview of the mathematical works that belonged to "the University Library of the City of Amsterdam." As far as we can see, all the works listed in the Mannoury catalogue are accessible via the current University Library of the UvA.
