Size: De collection comprises c.7,5 metres.
Access:In the Special Collections Reading Room a printed inventory of the collection is available. All letters in the collection have been recorded in the Catalogus Epistularum Neerlandicarum. However, as the inventory composed by D.J.H. ter Horst is very concise and by now incomplete, a new inventory has been drawn up by V.A.J. Klooster. A temporary print-out of it can be found at the Special Collections Reading Room.

In 1926, some years after the death of its last keeper, J.A.W.L. Cornets de Groot, the family archive was offered to the Koninklijke Bibliotheek on a permanent loan. Although the Koninklijke Bibliotheek is not the most appropriate place for family archives, the loan was probably accepted in part because its actual founder, Johan Pieter Cornets de Groot van Kraaijenburg (1808-1878), in his attempt to bring together as many records as possible concerning the (Cornets) de Groot family, also collected material about its most famous descendant, the lawyer Hugo de Groot (1583-1645). This material mainly concerns editions of his work, such as the Inleiding tot de Hollandse rechtsgeleertheyd (Introduction to Dutch law), and documentation about him from later periods. However, the central part of the archive consists of papers from the eighteenth and nineteenth century generations of the family, and contains, besides considerable amounts of correspondence, family papers such as testaments, inventories, genealogical surveys, decrees of appointment, etc. But one can also find more unusual objects, such as an extensive set of programmes of the Théatre Royal de La Haye. As some members of the family were, for longer or shorter periods, employed in the Dutch East Indies, the collection is in that view, too, a source of interest.
