This looks like a good read folks.http://www.centerforsocialmedia.org/resources/publications/code_for_media_literacy_education/
This document is a code of best practices that helps educators using media literacy concepts and techniques to interpret the copyright doctrine of fair use. Fair use is the right to use copyrighted material without permission or payment under some circumstances—especially when the cultural or social benefits of the use are predominant. It is a general right that applies even in situations where the law provides no specific authorization for the use in question—as it does for certain narrowly defined classroom activities.
This guide identifies five principles that represent the media literacy education community’s current consensus about acceptable practices for the fair use of copyrighted materials, wherever and however it occurs
Whilst its often the case that the copyright despots take no notice of the actual legaliities and fine print of the law( preffering instead the use of the computer generated "takedown" demand), you do have some limited rights to use certain sections or portions of certain works within certain settings , merely being aware of this is a threat to their monopoly so please read this folks and be aware of the grey line that exists when dealing with copyright restrictions.
