I would like to add to that the fact that we cannot purchase transactional licensing from Access Copyright. I get numerous requests from school boards who want to copy more than what the fair dealing guidelines allow and want to know how to do it. My answer has to be that you approach the author, publisher, or copyright owner directly. If they say no, then you do not copy. Your choice is to get permission, and payment where it's required, and if you cannot get permission and payment where it's required, you do not use that material. You find other material.
Nine times out of 10, people have to find other material because they cannot acquire a transactional licence.
