If you are seriously studying folklore or mythology, there is a good chance you will need to retrieve older (retrospective) articles that generally are not available online (JSTOR and Periodicals Archive are the exceptions).
Use the Illiad online module to request journal articles not available online. The articles will be sent to you via e-mail as pdf files. Let someone else do the work for you!
A full text journal collection that includes four important folklore journals: Journal of American Folklore, Journal of Folklore Research, Marvels and Tales, and Oral Traditions. Plus a large number of literature journals.
