The paper describes the upload of bibliographic records from the COBIB.SI shared database as well as holdings data of certain Slovenian libraries into WorldCat, the Online Union Catalogue. In 2009, the initial upload of records was made and a regular quarterly upload followed.
The import of bibliographic records for electronic books from Springer Publishing House to COBIB.SI is addressed in this paper. These records have been publicly accessible in COBIB.SI since October 2009. The suggestion to import them was given by the Central Technological Library at the University of Ljubljana.
Cataloguing rules strongly inﬂuence the quality of bibliographic data, which is made obvious through the COBISS system, where data has to be transferred to the system’s data format.
