Bibliografski zapisi iz COBIB.SI v WorldCat
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. Due to certain defects of bibliographic records in the Slovenian COBIB.SI shared database, not all records have been uploaded into WorldCat. The statistics of the records included according to various criteria in 2009 are provided at the end of the paper.
