JSTOR is a scholarly journal archive which provides full image access to articles from over one thousand leading academic journals across the humanities, social sciences, and sciences, as well as select monographs and other materials valuable for academic work. Journals are always included from volume 1, issue 1 and include previous and unrelated titles. JSTOR goes back to the very first issue of each journal (many of them in the 19th Century), but does not include the most recent five years.
