Subject-specific indexes and databases available via the USM Libraries homepage will help us to locate journal article citations (which provide just enough information to locate an article elsewhere), or, if we're lucky, full-text electronic versions of articles.
But don't limit your search to only what's available in full text. You may miss out on some important literature. And besides, even if you don't find the complete article in one of the library databases, there are convenient options for retrieving the article free of charge!
