JSTOR (pronounced JAY-stor; short for Journal Storage) is a digital library founded in 1995. Originally containing digitized back issues of academic journals, it now also includes books and primary sources, and current issues of journals. It provides full text searches of almost 2,000 journals. More than 8,000 institutions in more than 160 countries have access to JSTOR; most access is by subscription, but some older public domain content is freely available to anyone.
