Some publishers limit the number of readers who can use an ebook at the same time. This publisher-controlled limitation can make it difficult for an entire class to use the same ebook. Other ebook publishers offer better access choices.
Ebooks also vary significantly in price depending on whether the Libraries subscribe to the ebook or buy the ebook. In some cases, there are user limits on ebooks that the Libraries¹ own.
Before adding an ebook as a textbook to your course, check with your library liaison who can work with the Resources team to determine if a particular ebook will meet your needs. Not sure who your library liaison is? Check this list: http://util.library.dal.ca/Subspecialists/
