JStor, the online archive of academic papers, is trying out a program to let people see some of its content for free, reports Technology Review. The 70 titles that are part of this trial include the American Journal of Botany, PNAS, and the Royal Society's Proceedings: Biological Sciences, according to JStor. Tech Review notes that while people who take advantage of this free access program will be able to read articles, they won't be able to download or print them.
