These databases primarily search for articles. Books are also important sources for historical research. To find books, use the Randall Library catalog (to search books and ebooks at Randall Library) and WorldCat FirstSearch (to search books worldwide).
If you are looking for primary sources, be sure to also look through the Primary Sources for Historical Research guide.
The resources below are freely available databases that may include a variety of material: preprint (draft or preliminary) versions of articles, conference papers and/or posters, book chapters, white papers, and more. These repositories help speed up dissemination and enhance discoverability and access to early-stage scholarship across disciplines.
It is important to note that these materials have likely not been edited or benefited from the pivotal role of peer-review, which validates and improves the quality of final published journal articles.
