For those who really like wrapping their minds around issues of fair use from multiple vantage points, this is a must read:

Anthony Davis Jr. “Fair Use: Articulating the Liberal Approach.” portal: Libraries and the Academy 12.2 (2012): 121-137. 20 Jun. 2012.

And if that doesn’t grab you, you might enjoy getting re-fired up about the fact that you write scholarly articles for FREE while someone else profits from it. Also included, a mini-history about the origin of the notorious “ten percent rule” used or disregarded by reserve librarians.
