Q. Does fair dealing apply if the book I want to copy is out of print?
Although a book is out of print that does not mean it is no longer protected by copyright. Fair dealing for educational uses allows making copies of "small excerpts." If a substantial portion is required (see the Fair Dealing Guidelines for limitations), it is best to contact the publisher to either request permission to use the material and/or determine whether the work is still under copyright or has become public domain.
