Lookybook is quite an interesting site. It is online picture books.

You can read the book online then add it to your bookshelf. You can review it, rate it, share it, and /or purchase it.

You can search by author, title, illustrator, genre, subject etc.

They are not attempting to replace traditional picture books, but rather to complement them.
