JSTOR provides access to more than 12 million academic journal articles, books, and primary sources in 75 disciplines. This database serves as an archive of important scholarly journals and offers both multidisciplinary and discipline-specific collections. The articles are presented in high-resolution format, being archived as scanned images of journal issues and pages as they were originally designed, printed, and illustrated. Because of JSTOR's archival mission, there is a gap -- typically from 1 to 5 years -- between the most recently published journal issue and the back issues available in JSTOR.
