JSTOR This link opens in a new windowJSTOR is an indispensable database for academic research. Of its more than 2,000 journals, mainly in the humanities and the social sciences, there are 139 philosophy journals. In addition, there are more than 6,500 open-access ebooks from 85 academic publishers. Articles date from the 19th century to a "moving wall" of 3 to 5 years between the current issue and what is available on JSTOR. (Many publishers have similar restrictions to access, ranging from months to years.) In addition, JSTOR has what they call the Text Analyzer. Drag and drop your text in JSTOR's Text Analyzer, and it will suggest books and articles relevant to your paper.
