Google Books (previously known as Google Book Search and Google Print) is a service from Google Inc. that searches the full text of books and magazines that Google has scanned, converted to text using optical character recognition (OCR), and stored in its digital database. Books are provided either by publishers and authors, through the Google Books Partner Program, or by Google's library partners, through the Library Project. Additionally, Google has partnered with a number of magazine publishers to digitize their archives.

The Publisher Program was first known as 'Google Print' when it was introduced at the Frankfurt Book Fair in October 2004. The Google Books Library Project, which scans works in the collections of library partners and adds them to the digital inventory, was announced in December 2004.

The Google Books initiative has been hailed for its potential to offer unprecedented access to what may become the largest online body of human knowledge and promoting the democratization of knowledge. But it has also been criticized for potential copyright violations, and lack of editing to correct the many errors introduced into the scanned texts by the OCR process.

As of October 2015, the number of scanned book titles was over 25 million, but the scanning process has slowed down in American academic libraries. Google estimated in 2010 that there were about 130 million distinct titles in the world, and stated that it intended to scan all of them.

Results from Google Books show up in both the universal Google Search as well as in the dedicated Google Books search website (books.google.com).

In response to search queries, Google Books allows users to view full pages from books in which the search terms appear, if the book is out of copyright or if the copyright owner has given permission. If Google believes the book is still under copyright, a user sees "snippets" of text around the queried search terms. All instances of the search terms in the book text appear with a yellow highlight.

The four access levels used on Google Books are:

In response to criticism from groups such as the American Association of Publishers and the Authors Guild, Google announced an opt-out policy in August 2005, through which copyright owners could provide a list of titles that it did not want scanned, and Google would respect the request. Google also stated that it would not scan any in-copyright books between August and 1 November 2005, to provide the owners with the opportunity to decide which books to exclude from the Project. Thus, Google provides a copyright owner with three choices with respect to any work:
