The most reliable method for linking to content is to use the permalink feature in the library's discovery platform, OneSearch.
After locating the item in OneSearch, click on the 3 dots in the right corner of the search result.
Next, click on the button labeled permalink
Finally, click "Copy the Permalink to Clipboard" and then paste that link into canvas or the other
While it will require 1 extra click for you and others to access the full text, the benefit is that the catalog's permalink will always be the most reliable way to get access to library-licensed and owned digital content.
