The gradual realization by Günter Schilder of his monumental series Monumenta Cartographica Neerlandica is dealt with here, on the basis of interviews with the author. At an early date its aims were established as: the unveiling and inventory of the map and atlas production in Amsterdam in the late sixteenth and early seventeenth centuries, focusing on the Dutch participation in the early geographical discoveries, and the conservation, restoration and the production of facsimiles of those maps in order to safeguard this material for the future. The selection of the material is accounted for, both regarding the publishers and authors and the selection of map types. Input by three different publishing houses (Israel, Canaletto and Hes & De Graaf) during this project is indicated as well. The series was completed by volume IX. To improve access to the whole series a general index of personal names, maps by region and a dozen thematic subjects covered by all nine volumes has been compiled.
