Doctoral students go through an exhaustive literature search when writing their dissertations. They also tend to work on new questions, sometimes ones that have received very little attention from scholars before. You can obtain many of these dissertations and benefit from all the bibliographic treasues and new ideas. Check ProQuest Dissertations & Theses to identify dissertations on your topic.
How to Use Subject Headings:
Sample subject headings include:
To search directly for a subject heading, go to Tripod and change the drop-down menu from "Keyword" to "Subject." Enclose the subject heading in double quotes and then search.
To find books that are not owned by the TriCo libraries, search by keywords and/or subject headings in WorldCat, and make interlibrary loan or EZ-Borrow requests. Whenever possible, try to make your interlibrary loan requests early in the semester, to ensure that the books arrive with enough time left to write your paper.
