Google's new service is similar to the one announced by Amazon.com earlier this year. Under the rules announced this morning by Google, publishers can submit their books to Google for indexing, in return, Google will scan their book and provide a listing in their engine at no cost to the publisher.
When a search term is entered into Google, the engine will return results that display links to the book. By clicking on the book title, the user will be taken to the Google content page, where a portion of the book will be available for reading online. Links to purchase the book from online book sellers will also be made available.
Google won't receive a commission on the sale of a book, however, they will provide contextually targeted ads on "Google Print" book pages; and revenue earned from these ads will be shared with the book publishers.
There is no specific mention of genealogy books in the announcement. However, one would assume that new genealogy books can be submitted by the publishers and/or authors.
