Just in time for the expected Kindle 2 announcement, Google is apparently trying to steal some of the pre-announcement hype by launching its own mobile book reading service. Previously available on for desktop computers, Google Book Search is now available via a new mobile web site, providing on-the-go access to nearly 1.5 million public domain books. Point your mobile browser to books.google.com/m where you can peruse its book list via category, find the poplar titles in the “Featured Books” list or search by author, title or subject. The web site is optimized for Android and the iPhone and they are currently the only supported mobile platforms with no indication as to whether or not mobile Book Search will be expanded to support Windows Mobile, S60, Palm or Blackberry. Most Google products end up being extended to those platforms so we assume that same principle will apply here but for the time being, G1 and iPhone owners can flaunt their ability to read the Adventures of Sherlock Holmes for free while riding the morning subway to work.
