In a nutshell, JSTOR is a massive database that contains journals, books, images, and primary sources. I have found many college and university databases that use JSTOR as their primary database collection provider.
From the site:
JSTOR provides access to more than 12 million journal articles, books, images, and primary sources in 75 disciplines.
We help you explore a wide range of scholarly content through a powerful research and teaching platform. We collaborate with the academic community to help libraries connect students and faculty to vital content while lowering costs and increasing shelf space, provide independent researchers with free and low-cost access to scholarship, and help publishers reach new audiences and preserve their content for future generations.
In my opinion, it is a “must research” set of databases that genealogists should include in their repertoire.
