History

Complementing the better-known JSTOR with a more international orientation, PAO is a archive of more than 700 periodicals in the humanities and social sciences since their first issues. More than 150 are in languages other than English. Coverage is from volume 1, issue 1 of each journal, and all issues are digitized from cover to cover.

JSTOR (from Journal STORage) is an archive of academic journals in the humanities, social science, and sciences, from earliest issues up to 3-6 years before present. So for some purposes, it is a collection of secondary sources and for others, primary sources.
If you want to do a comprehensive, up-to-date search of the literature on a topic, don't begin in JSTOR; start in a discipline-specific database instead. JSTOR articles are exact facsimiles of originally as originally printed: they will include information may be obsolete and may use words that have shifted meaning and/or have become regarded as inappropriate, incomplete, or worse. But if you want to know what scholars in, say, the 1930s said about controversial topics like race, some religious traditions, gender and sexuality, or mental or physical impairments, you will need to use search terms that match words of that time, not ours, even though they may offend you deeply.
