The records from RERO, an acronym of REseau ROmand, the Library Network of Western Switzerland, represent mainly French-, English- and German-language materials. OCLC will provide import capabilities for cooperative cataloging for the 215 RERO libraries along with increased visibility of the libraries’ collections on the Web. This is the third major addition of records for French-language materials to WorldCat in recent months. OCLC announced in June that the Bibliothèque nationale de France (BnF) was adding 13.2 million records to WorldCat. In September, ABES (l’Agence Bibliographique de l’Enseignement Supérieur) signed an agreement to add 9 million records from Système Universitaire de documentation (Sudoc), the cataloguing system for French academic libraries managed by ABES, into WorldCat.
