Budapest University of Technology and Economics (BME), Institute of Mathematics Library

The Institute of Mathematics Library at Budapest University of Technology and Economics replaced its CDS/ISIS for Windows 1.4 catalogue with Koha in May 2013. Its institutional migration account describes the preceding system, the conversion work and the final data transfer. Staff exported the ISIS records as XML, cleaned and converted the data to MARC21, and loaded the resulting records into Koha. The account reports that 23,125 bibliographic records remained after removal of previously discarded books and were transferred without bibliographic data loss. The library’s own report presents the change as a move to an open-source, Linux-based integrated library system. This documented migration is specific to the Institute of Mathematics Library, rather than a migration of all BME libraries.
