This article is about Google’s book search engine. Books are provided how to use a pdf in google classroom offline 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 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. 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. In-print books acquired through the Partner Program are also available for full view if the publisher has given permission, although this is rare.
For in-print books where permission has been granted, the number of viewable pages is limited to a “preview” set by a variety of access restrictions and security measures, some based on user-tracking. Usually, the publisher can set the percentage of the book available for preview. Users are restricted from copying, downloading or printing book previews. A watermark reading “Copyrighted material” appears at the bottom of pages.
All books acquired through the Partner Program are available for preview. Google does not have permission of the copyright owner to display a preview. This could be because Google cannot identify the owner or the owner declined permission. If a search term appears many times in a book, Google displays no more than three snippets, thus preventing the user from viewing too much of the book. Also, Google does not display any snippets for certain reference books, such as dictionaries, where the display of even snippets can harm the market for the work.
Google maintains that no permission is required under copyright law to display the snippet view. Google also displays search results for books that have not been digitized. ISBN, subject and copyright information, and in some cases, a table of contents and book summary is available. In effect, this is similar to an online library card catalog. 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.
