"Federated searches" means searching more than one database at the same time. In WGSS this could be useful because your topic could be interdiscipinary. We have two broad federated search engines to try:
OneSearch: allows you to search our book catalogs plus most of our databases.
Ebsco (all): search our top ebsco databases at once (Communications, LGBT Life, SocIndex, PsychInfo, Academic Search Complete, more)
