The library offers research and teaching materials electronically through nearly 300 databases and many more direct subscriptions to e-journals. Most of this content can be accessed by an unlimited number of simultaneous users and you can add links to these articles, news pieces, streaming recordings, and primary sources to your Canvas site with reckless abandon, with rare exceptions.
When adding links to library-provided content in Canvas, there are some important logistics to consider re: off-campus access. If you do not want to deal with these tasks, you can ask library staff to do it for you through a Course Reserves request (see below).
