Today Amazon officially launched its Matchbook service that we reported on a while back. The service offers electronic versions of hard copies of books customers purchase for an additional $3 or less. Amazon says that the service is retroactive and any books you have purchased over the years qualify if they are in e-book form.
The books are in Kindle format and include all the features one would expect when buying a book for their kindle. Whispersync, X-ray and everything else functions as normal. The company says that it will continue adding titles to the service and new releases will be added as well. Personally, I love this new service. Last year I lost my entire book collection when my home was destroyed in a fire, and now I can go to Amazon, and replace a lot of those books in digital form for just $3 each!
