The Koninklijke Bibliotheek holds over 120 km of written heritage, ranging from 'Donald Duck' to legal codes, from literature to rare books in its special collection. To mark the KB’s 225th anniversary, Anne Geene made a random selection from this archive using an algorithm created by Erik Vos (a data specialist at the KB). This process resulted in the selection of 225 books, with page 225 of each book reproduced. This collection reflects the diversity of the books held at the KB.
