​Cataloging and Classification Department


The department is responsible for creating information describing the collections as it appears in the libraries' catalog. The catalog serves as a database of records that include bibliographic data, subjects, item holdings and the locations of the items in the Technion's libraries.

We work according to international cataloging and classification instructions and standards as in other academic libraries in Israel and worldwide. The cataloging is done according to RDA instructions (formerly AACR2) using the MARC standard while subject classification is done using the UDC scheme.

We catalog items that have been purchased by the Technion's libraries, theses, donations, and old uncataloged items such as research reports. In addition we are responsible for adding to the catalog publishers' packages of electronic books and periodicals, which were either permanently acquired or received for a trial period. The cataloging process includes the creation of authority file records for persons and corporate bodies associated with the cataloged items.

Codes entered into the bibliographic records enable the retrieval of items according to format (print, electronic…), material type (books, films, maps…), textbooks, holdings, new arrivals, and more. Those codes are also used for statistical purposes when needed.

According to the libraries' policy of collection evaluation we delete the records of discarded items from the catalog, so that the content of the catalog always displays the actual holdings of the libraries.

The subject classification reflects the content of the cataloged items. Content subjects are represented as textual phrases associated with UDC numbers, and are managed in a subject authority file. The UDC numbers also serve as shelf marks. All library items are classified except for those on a trial basis.  

Whenever required, subjects are updated (new ones added, textual phrases or UDC numbers changed) or deleted according to the developments in the libraries' collections and within the subject authority file itself.

We also process items acquired for and held by the Central Library including stamping, labelling and book binding as necessary.
