The expert search allows users to search an element in a precise MARC21 field or sub-field. This search is intended for users with a good knowledge of MARC21 and of the Register, and is restricted to subscribing users.

Select the search field from the pull down menu, and enter a MARC21 code.

Ex: to search all daily resources, select the field “Frequency” and enter the coded value “d” for “Daily”;

To search all blogs, choose the field “ROAD code” and enter the value OA-B.

To search for a subject, select the classification of your choice (Dewey or UDC) and enter the specific classification index required.
Ex: to search for “film music”, enter the Dewey classification index “781.542”.
