The databases below allow you to search for journal articles by subject. When you find a title of interest, if the full text is not immediately available (as in JSTOR and Proquest), use the Find It button to check for Haverford's holdings.
See the Search Tips tab for examples of ways to develop terminology and construct search statements.
Usually researchers find more sources by looking at the footnotes in an article or book, but these will always be older than the publication you have in hand. Citation indexes like the Web of Science (which includes sections for the Social Sciences, Arts and Humanities, and Science) are set up to search for sources cited in the footnotes of journal articles as soon as they become available.
This allows you to find newer articles which cite the books and articles you already know are key for your topic. By relying on connections between authors rather than subject words and by moving forward in time, citation searching can open up new avenues of research.
