On December 28th the Congressional Research Service (CRS) released a six page research report that looks at online indexing, law, fair use, and the Google Book Search project. The full text of the report is available here.
The Congressional Research Service (CRS) is one of the most respected names in research. You name the topic and they prepare reseach reports on it. CRS is located here in DC at The Library of Congress. Many of their reports are difficult to access (that's another story) but thanks to various organizations like the Open CRS Project, the Federation of American Scientists, and National Library for the Enviroment, the IP Mall collection, it's getting a bit easier. One caveat is that CRS reports are frequently updated so make sure you're reading the most current version possible. Thanks to S.B. for the news tip.
