Education blogger John Battelle offers a look at comments from a letter by University of Michigan President Mary Sue Coleman defending Google’s Book Search project, which critics contend violates the copyrights of publishers and authors who should receive royalties whenever their works are viewed in full on the internet. In her letter, Coleman defends the project, saying it has immense educational value for schools and students in particular. “We believe copyright law allows us the fair use of millions of books that are being digitized,” wrote Coleman. We are allowing Google to scan all of our books–those in the public domain and those still in copyright–and they provide our library with a digital copy. We insisted on this for one very important reason: Our library must be able to do what great research libraries do–make it possible to discover knowledge.”
