has introduced a new "search inside the book" feature, with help from book publishers.

This innovative search feature lets Amazon customers search the full text of a title to find a book, supplementing the existing search by author or title.

Amazon has launched the service in the US with access to the text of 120,000 titles. Customers can also preview the inside text of books.

Amazon CEO Jeff Bezos said: "Innovation drives customer experience, and Search Inside the Book is a great example. With publisher's help, we are offering a completely new way for people to find the books they want."

Amazon UK has so far been unable to confirm if it will deliver this feature in the UK.
