Wade into your research, and then contact staff (e.g., for ECLS) who can assist in answering questions. Check out the bibliographies that are put up at the survey websites. You can also check into adding a citation to your published findings to these bibliographies.
Search on the title of the study as well as the acronym for it. Look into the "exact phrase searching" capabilities of the databases you use.
Once you find a few good papers or documents, use library databases to locate other documents--published later in time--that *cite* them. A great way to build bibliography. A librarian can help you with this.
Look for heavily cited articles to get a sense of important/high impact research in your area of interest.
Re. PsycINFO: Use the "Term Finder" in PsycINFO to search for "memory", then look at the narrower terms under that broad term for more specific topics relating to memory.
See the page tab for library guides. These identify library resources in various subject areas.
In the subject guide for Psychology, note the section about review article sources. Review articles provide a great way to get an overview of a particular topic and can lead you to good bibliographic citations. Also see the tab about reference tools.
