Copyright is a legal right given to the author of a work allowing him to profit from said work. This does not forbid anyone else from reproducing the work but put limits on how this can be accomplished. The copyright law allows the fair use of an protected material. For example you can reproduce the sound recording of your bought compact disc but it is illegal to give away such a copy to a friend. However, it is legal in Canada to reproduce copyrighted material in a report if it falls under the fair use clause of the copyright law. As it pertains to us, fair use implies that the material is properly attributed to its original author, that it is less than 15% of the total original work and that the new work in which the copyrighted material is to be reproduced is to be used solely for educational or research purposes.
