You will need permission to repeat the copying. However, if it will be sold, for example as part of a course packet or syllabus, you do need permission, no matter what the length. If the work is in a book published after that date, be careful that the version is not different from the original. If it is, then the author has copyright rights to that version. If it is not yet in the public domain, Copyright protection still exists.

Y ou cannot. Also, you cannot copy substantially from a work even if you have purchased it. According to the Library of Congress Copyright Office, syndicated cartoons may not be copied even once. Many syndicated cartoon characters are protected by both copyright and trademark. Do not use syndicated cartoons merely to add humor to handouts, tests or presentations.
