In this "Dictionary," more than four hundred biographical entries encompass all the Dutch thinkers who exercised a major influence on the intellectual life of the Golden Age, as well as those who developed their ideas and beliefs through interaction with other scholars. Additional entries describe foreign philosophers who lived in the country temporarily and whose work was influenced by their stay. These include John Locke, Rene Descartes and Pierre Bayle.

Two separate Dutch translations, with introduction and notes, of the Monadology were published in 1991: Monadologie of de beginselen van de wijsbegeerte, translated by Dr. F.P.M. Jespers of the Universiteit voor Theologie en Pastoraat in Heerlen and De Monadologie. Over samenhang in het universum, translated by H. Boering and H.C. Meinsma. These are the first Dutch translations of the Monadology.
