JURN (www.jurn.org) worthwhile when performing article searches.
It uses a Google custom search engine to cross-search resources found on sites such as Intute and DOAJ (Directory of Open Access Journals) as well as a large number of individually selected titles. The end result is a federated search tool covering over 4,000 open access titles. It provides a useful and focused way to broaden your article search beyond those e-titles available through our journal and/or database subscriptions.
Sample titles include Americana: The Journal of American Popular Culture, Tympanum: A Journal of Comparative Literary Studies and Aether: Journal of Media Geography but you can see a full list of titles included here.
