Q. Can I post a document I obtained through interlibrary loan to my Canvas course?

In general, no.

If Interlibrary Loan borrowed the document from another library, under the library copyright exception, it was obtained for your personal use and cannot be further distributed. It likely has a cover page that states this restriction.

Interlibrary Loan can probably purchase a copy that allows for limited redistribution, such as in a restricted access Canvas course. If you need to share a document with your class to which the library has no access, include this information in the notes field of your ILLiad request. We'll make our best effort to obtain a copy you can post in Canvas.
