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.
