1. Use this guide as a starting point. Begin your search with the resources linked from the Psychology subject guide. These library catalogs and databases will help you identify what's been published on your topic. Pair these resources with open access resources such as Google Scholar and Directory of Open Access Journals and our library ILL service.
2. What came first? Try bibliographic tracing. As you're finding sources, pay attention to what and whom these authors cite. Their footnotes and bibliographies will point you in the direction of additional scholarship on your topic.
3. What comes next? Look for reviews and citation reports. What did scholars think about that book when it was published in 2003? Has anyone cited that article since 1971? Reviews and citation analysis tools can help you determine if you've found the seminal works on your topic--so that you can be confident that you haven't missed anything important, and that you've kept up with the debates in your field. You'll find book reviews in JSTOR and other databases. Google Scholar has some citation metrics.
4. Stay current. Get familiar with the top journals in your field, and set up alerts for new articles. If you don't know where to begin, APA and other scholarly associations often maintain lists of journals, broken out by subfield. In many databases (and in Google Scholar), you can also set up search alerts, which will notify you when additional items have been added that meet your search criteria.
5. Stay organized. A citation management tool--e.g., RefWorks, Endnote, Zotero, Mendeley--will help you store your citations, generate a bibliography, and cite your sources while you write. Some of these tools are also useful for file storage, if you'd like to keep PDFs of the articles you've found. To get started with citation management tools, check out the resources listed on the "Citation" tab.
