If you identify a reference to a useful conference paper, you could begin by checking WebCat to locate a paper copy. Note, however, that the Library holds few conference papers in the Social Sciences.
You could also try searching the Internet for the full-text as many recent conference proceedings are made freely available online.
If you are unable to find the paper you need either in the Library or online, you may be able to borrow a copy via Inter-Library Loan.
Use a database to search for references to conference papers.
