JSTOR announced it is opening the door to its formerly closed world of academic publications a bit. It has made a substantial collection of academic articles published prior to 1923 available to anyone, free of charge.
To access these early papers, as the video below explains, go to JSTOR's site and click on "Search," then on "advanced search." Then, click on the box next to "Include only content I can access." Type in your search terms and anything that appears can be read online, or downloaded as a pdf. You'll be asked to accept JSTOR's Terms and Conditions.
