While you point to the change made after the last review, it actually dates from earlier than that because the Supreme Court has been providing jurisprudence on the use of fair dealing since 2004. It just took a bit of time for universities to adapt to those changes.
For us in universities and university libraries, there are a variety of benefits to having a very a liberal fair-dealing exception. For one, it really helps instructors in the way they compile course materials. They can take materials from a variety of different places and compile them all together; they can use materials on the fly; and they can build a course that really works. As we mentioned, universities have been putting together a variety of systems to help instructors do that. That's a real way it has benefited us.
A liberal fair-dealing exception also benefits researchers in a variety of ways. They can use and reuse copyrighted material in their research. In addition, we use it in the library in a number of ways as well, and inter-library loans is one.
