It's not just plagiarism you have to be concerned about. At Oklahoma Christian University, you will be expected to use copyrighted information appropriately. If you use a work without receiving permission from the creator, you are committing a major offense, you have violated copyright laws.
Copyright not only protects published authors and corporations who have unique products, like Disney's Mickey Mouse, it also protects individual creators like professors and students. Every time we produce something unique, our work is automatically protected by copyright...with or without a © symbol.
Just because a book is out of print does not mean it is no longer under copyright and you have the right to copy it.
