In addition to books and periodicals, the unique collection of the NSZL also includes special small graphic works: the national library has an ex libris collection of both old and modern works, which is outstanding both nationally and internationally.
The newly launched online content service of the NSZL called Könyvjegytár [Bookplate Collection], is the first to make freely accessible the nearly 1,100 old ex libris holdings of the Early Printed Book Collection and the 3,400 documents and therr variants of the 10,000-item collection unit of the Map, Poster and Small Print Collection, which is organised by collector's name.
