Hannibal Travis has self-archived "The Economics of Book Digitization and the Google Books Litigation."
Here's an excerpt from the announcement:
This piece explores the digitization and uploading to the Internet of full-text books, book previews in the form of chapters or snippets, and databases that index the contents of book collections. Along the way, it will describe the economics of copyright, the "digital dilemma," and controversies surrounding fair use arguments in the digital environment. It illustrates the deadweight losses from restricting digital libraries, book previews, copyright litigation settlements, and dual-use technologies that enable infringement but also fair use.
