Journal articles provide in-depth scholarly information. They are vetted and improved by peer review. They are usually fairly short in length and often focused on discussing one specific issue. They are well documented with footnotes citing relevant scholarship and primary sources. The indexes listed below are good places to find journal articles about history.
When you find an article of interest, if the full text is not immediately available, use the Find It button 
to check for Haverford's holdings. If we do not have a subscription for that journal, you will be able to request a digital copy.
See the Search Tips tab for examples of ways to develop terminology and construct search statements for journal index searching.
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.
