For those of us that aren’t based out of a university—and even for many who are—finding research resources that cover the topic you're interested in can be a challenge.

In fact, many world-renowned libraries and magazines are now working to digitize important parts of their collection, while a number of online organizations have sprung up with missions to improve access to information. To help you identify some of the most useful, we’ve put together a list of 18 free websites that offer scholarly articles, publications, photos, videos, and much more.
