Uppsala University Library owns a large number of early imprints from Poland or relating to Poland.

The Polish books in the Incunable Collection and in the Copernicus Collection are described in printed publications. Józef Trypucko made an inventory of all the Polish works earlier than 1800 held at the Uppsala University Library in Polonica vetera Upsaliensia. With the exception of the above, early Polish books do not constitute a special collection but rather are spread among other early works.
