When you are off campus, you will need to set up a Proxy or VPN (Virtual Private Network) on your computer to gain access to the Library's licensed resources, such as e-books, e-journals, and article databases. Directions are here.
Find books, textbooks and journals on your topic in the UCSD Libraries' catalog, Roger.
Include "textbook" as a keyword to find textbooks. Limit to "Journals and Serials" to search for journal titles. Use Citation Linker if you have a specific journal article citation. Locate books outside of UCSD with Circuit (SD area), Melvyl (UC libraries & beyond).
Find journal articles on your topic. In some databases you'll find conference papers as well.
Use UC-eLinks to located the full text of articles, if the Library licenses it. Or find the print copy in the Library collections.
Google can give you a start on your research, but using Google Scholar is smarter. You'll search only academic resources, and if you set you Scholar Preferences to "University of California, San Diego - UC-eLinks" you'll be able to use UC-eLinks to get to article PDFs when you're off campus.
As you do research, you'll accumulate journal and book citations that you'll want to keep organized. Refworks is a free online web tool for managine your references. Sign up for a Refworks account and take a library workshop on how to get the most out of it.
