The University of Michigan has hit the “one million books scanned” milestone. As far as I know Michigan is the first library to have one million books from its own collections digitized and available for search (and, when in the public domain, available for viewing.)
For more about the scanning project generally including some insight into why people call it controversial, there’s a good long article from Campus technology (link to printable version, all on one page) which gos into the logistics of the scanning program in some depth.
When it comes down to it, then, this brave new world of book search probably needs to be understood as Book Search 1.0. And maybe participants should not get so hung up on quality that they obstruct the flow of an astounding amount of information. Right now, say many, the conveyor belt is running and the goal is to manage quantity, knowing that with time the rest of what’s important will follow. Certainly, there’s little doubt that in five years or so, Book Search as defined by Google will be very different. The lawsuits will have been resolved, the copyright issues sorted out, the standards settled, the technologies more broadly available, the integration more transparent.
