JSTOR offers interdisciplinary content to support scholarship and teaching. It includes 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. Typically, coverage ends 3-5 years before the present date, a "moving wall" system that protects publishers from last revenue for recent articles.
