Know Your Copy Rights brochure (pdf file) explains what faculty can do in making works available in their teaching. See also its FAQ at the end. Pub. by the Association of Research Libraries
What can faculty safely place in Canvas?
Best Practice: submit library reserve requests, then, in canvas, link to that single course reserve link for your course's items. By doing this, the library checks on and seeks permissions and pays fees.
Links to materials found on the open Web.
Link to or embed code to a video from any of the Library's streaming documentary films.
Permalinks or URLs to any of the Library's full text journal articles from its databases (do not place the pdf files in Blackboard).
Up to 10% of a copyrighted textual work for which you have a legally obtained print copy. (You have to scan it yourself, unless you make a course reserve request through the Library. In the latter case, library staff will do the scanning and place the item on e-reserve in the Library site. Library staff will also take care to check on fair use.)
