Collection searches

ULB’s valuable historical holdings and collections can be searched via the library’s catalogue. The library’s manuscript and incunabula collections have already been digitalised, so you’ll also find these in ULB’s Digital Collections. We provide links to various search tools here to enable you to also search for manuscripts, incunabula and early prints stored at other libraries.


The private collections kept at ULB are not listed in the library catalogue, but rather are recorded in the Kalliope Union Catalogue.
