These databases specialize in locating articles in scholarly/academic journals and related sources.
Here are databases which specialize in searching and providing texts of newpaper articles published from the 1990's to date. (You can occasionally find older articles.)
A prominent new option on the library's homepage is a database called Primo, which is an attempt to present all the contents of our databases in one search tool, but it does NOT provide you with access to everything to which the library subscribes. It's fine as a starting point, but probably will not adequately cover a lot of research topics.
