According to Stanford's Copyright and Fair Use summary (http://fairuse.stanford.edu/overview/fair-use/cases/) that Twin Peaks case might not be the precedent they say it is.
Not a fair use. A company published a book entitled Welcome to Twin Peaks: A Complete Guide to Who’s Who and What’s What, containing direct quotations and paraphrases from the television show Twin Peaks, as well as detailed descriptions of plots, characters, and setting. Important factors: The amount of the material taken was substantial and the publication adversely affected the potential market for authorized books about the program. (Twin Peaks v. Publications Int’l, Ltd., 996 F.2d 1366 (2d Cir. 1993).)
