University of Białystok, Jerzy Giedroyc University Library

In September 2025, the Jerzy Giedroyc University Library at the University of Białystok announced that Koha was working as its new library system after nearly thirty years with ALEPH. The library says Koha provides the online catalogue and supports reservations and account access. Its announcement also documents integration with the university’s USOS authentication service and a unified system across the library network. The source establishes the change from ALEPH to Koha, but gives no technical account of record conversion, crosswalks, or data-loss testing. The case is therefore a documented system transition without claims about the underlying migration method. Separately, the University of Białystok operates RUB, an institutional repository using DSpace. The repository policy identifies DSpace and cites the 2013 rector’s ordinance; the live repository contains populated records. This repository is a distinct service from the library’s Koha catalogue.
