Congress recognizes the needs of educators to use copyrighted materials to teach effectively. To protect educators and educational uses in general, the Copyright Act includes several exceptions to protect educational uses of copyrighted materials. None of the following replace the fair use provision of the Copyright Act, so if your intended use does not fit within one of these categories, it may still be protected as a fair use.
Section 110(1) of the Copyright Act explicitly permits the "performance or display of a work by instructors or pupils in the course of face-to-face teaching activities of a nonprofit educational institution." A legally-obtained copy of a particular work may be displayed or performed in a classroom, or similar place devoted to instruction. This broad limitation on the exclusive rights of copyright owners applies to any copyrighted work which may be displayed or performed, so long as the work is relevant to class instruction.
University licensed works
The IU Libraries pay for licenses to give you access to hundreds of different research databases, providing students and faculty access to thousands of copyrighted works. As the vast majority of the library licenses allow for the use of materials for e-reserves, you may link to the library's licensed copy without any other copyright considerations. There are some exceptions though (most notably the Harvard Business Review) where linking to an article is not allowed.

Section 110(2) of the Copyright Act, also known as the TEACH Act, extends part of the face-to-face instructional display and performance exemption to distance education transmissions. The TEACH Act does have significant limitations on what and how much of a work may be shown, whereas the classroom teaching exception does not. To qualify under the TEACH act, an instructor must use a lawful copy and meet the following conditions:
If these conditions are met, the material copied is limited to:
Some materials are excluded from the TEACH Act, including works primarily "produced or marketed primarily" for distance education; works the instructor "knows or has reason to believe" were not lawfully reproduced; works protected by "technological measures used by copyright owners to prevent...retention or unauthorized further dissemination"; and textbooks, coursepacks and other material typically purchased by students. If a particular use does not qualify as an exception under the TEACH Act, it may still be protected by fair use.
The TEACH Act also requires that technological measures must be taken to prevent retention of the work for longer than the class session and unauthorized further dissemination of the work. These requirements, especially the second, are difficult to meet, so many universities do not rely on this section of the law but instead rely on fair use.
