Google Books 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, and stored in its digital database.
Searching books with Google Books is analogous to searching websites with «Google Web Search». If a publisher or author has given the permission, a full page is shown allowing to browse within the book and to see more pages. If the book is out of copyright, it is possible to page forward or back to see the full book. Clicking on Search within this book allows you to perform more searches within the selected book.
Note: For an export of the bibliographic details related to a specific book, you need to click on «About this book» and scroll all the way down to «Export Citation».
