To access the advanced search feature, click the OneSearch image on the Library's homepage and then the "Advanced" search link next to the Basic Search bar. A set of radio buttons gives you the option to search just the CSUN Collections, Course Reserves, or All CSU Libraries, which includes items you can order through CSU+ or InterLibrary Loan. You can search by Title, Author/contributor, Subject or ISBN, or all fields, and can combine multiple search statements. You can limit your search by Material Type (Books, Articles, Journals, Images, or Audio-visual), but language, and by date or date range.
