Passe-partout: international bank of decorative illustrations of printing

Passe-partout, an international bank of decorative illustrations of printing, created in 1997, is presented as a metacatalogue that allows the retrieval of a typographical illustration from within a corpus of several thousand images, with the aim, for example, of identifying an edition published under a fictitious address. Two kinds of search are possible: one traditional, by means of semantic descriptors; the other, more revolutionary, with the aid of a computer graphic comparator.
