As expected, Google has launched a digital store called Google eBookstore that will provide Google eBooks in the US. The search giant is claiming it has the largest collection of ebooks in the world: more than 3 million titles, hundreds of thousands of which are available for sale. The company has partnered with independent booksellers that will sell Google eBooks: Powell's, Alibris, and participating members of the American Booksellers Association.

Google eBooks is compatible with laptops, netbooks, tablets, smartphones, and e-readers. The Google eBooks Web Reader lets a user buy, store, and read Google eBooks in the cloud. All you need to do is sign up for a free Google account and you'll get unlimited storage for your digital books. Google is also planning on releasing free apps for Android and Apple devices to buy electronic books and read them on the go. Many books will let you select a font, font size, line spacing, day or night reading mode, and let you pick up on the page where you left off when switching devices.

Since Google launched Google Books in 2004, the search giant has digitized more than 15 million books from more than 35,000 publishers, more than 40 libraries, and more than 100 countries in more than 400 languages. That information is available via Google Books search in the research section alongside the ebookstore.
