Language is an important factor of economic development; translation and localisation are necessary for the overall progress and economic development. In the European Union, language is key and English is no longer sufficient for the development of a common language policy; they are now striving to achieve a situation where every European would speak at least two foreign languages. In science, the number of publications in the researchers’ mother tongues has increased and publishing in English is no longer a sign of prestige.
Library catalogues allow users searching of library materials in different ways. To achieve successful and efficient searching, bibliographic and authority records should be created according to cataloguing rules, besides perfect and accurate records are required. That is why, cataloguers are responsible for an adequate quality of records and the quality control should be regularly examined.
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.
Library development depends on rapid changes in the environment, such as pressure on budgets, personnel and space, and much higher expectations of users. Libraries, therefore, have to focus on virtual space where users’ eyes are.
