Cataloging is done according to predetermined rules that are used in libraries in Israel and worldwide.
In summer 2014 new and updated cataloging rules have been introduced (RDA - Resource Description & Access) based on a new concept that will change the way information is presented to the public.
Information about library materials (books, CDs, maps, etc.) will be handled hierarchically with the original work at the top and below its products (eg editions of the original work) down to the level of the item / copy. The relationships between the products of the relevant cataloged material will be reflected to include: people involved (individuals, families and organizations / corporations) and subjects (concepts, objects, events and places) , and thereby will create a database and not just an inventory.
