To find out which of these databases carries a particular journal, use the more comprehensive Full Text Finder database of journal (and e-book) titles. This database will also tell you whether a title has expired or not, how far back the back files go, and what the embargo period is, if there is one.
See our library staff if you need help using these resources.
