Size:The Koninklijke Bibliotheek owns a collection of letters of approximately 125,000 to 150,000 items from the beginning of the seventeenth century to the present. Letters from the nineteenth and twentieth centuries are by far the most numerous among them.
Accessibility:Apart from the letters in a few extensive archival items, all letters in the Koninklijke Bibliotheek have in principle been described in the Catalogus Epistularum Neerlandicarum. The records were made on the basis of the alphabetical card catalogue in the Department of Special Collections. Cards that contain insufficient information have been omitted. As the final check has not yet taken place, it is useful to check not only the CEN but also the alphabetical card file.

With respect to the modern men and women of literature there are agreements with the Letterkundig Museum: in this field the Koninklijke Bibliotheek merely complements those files that have been in its possession for a long time. Among the artists we can mention the painter Jan Toorop (1858-1928), the painter and etcher Willem Witsen (1860-1923) and the composer Willem Pijper (1894-1947). Furthermore there are small files on figures such as the painters R.N. Roland Holst (1868-1938) and Dick Ket (1902-1938). Politically orientated collections are, amongst others, those of Ch. Fr. Lebrun (1739-1824) and L.W.C. Keuchenius (1822-1893). Besides, there are a few extensive collections of family letters, e.g. in the archive of Cornets de Groot and the circle of family and friends around A.J. Enschedé (1829-1896). Furthermore, there are numerous, more or less individual letters which have entered the Koninklijke Bibliotheek as part of the collection of a collector of autographs, for example that of G.J. Beeldsnijder van Voshol (1791-1853).
