The other half of cataloguing: new models and perspectives for the control of authors and works.

Electronic catalogues makes retrieval of specific records very simple in most (not all) cases, but a reliable retrieval of all material answering a well-defined need is still tiring and sometimes impossible in crowded bibliographic databases. Authority control still is the “poor relative” of cataloguing. Cataloguing rules do not make clear the difference between the access points for bibliographic records and the relationships (work-to-work, author-to-work, etc.) that are independent from specific publications.
