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.
