The library databases contain journal articles and other scholarly information. Sometimes a database will contain the entire journal article, and sometimes it will only contain an abstract. Databases are searchable by subject, keyword, author, and more. They can be seen as the tool that you use to search and access scholarly publications, such as peer-reviewed journal articles.
You may notice that the database doesn't always provide you with a PDF of the article -- sometimes it will just give you an abstract. In that situation look for the "Find it @ W&M' button, which will take you back through our library website to get you access to the article. If it's something that we don't have, you can request it by interlibrary loan. They'll send a PDF of the article straight to your inbox, typically within a few days!
