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 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.
Results from Google Books show up in both the universal Google Search and in the dedicated Google Books search website books. 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 GuildGoogle announced an opt-out policy in Augustthrough 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 Novemberto 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: .

Most scanned works are no longer in print or commercially available. In addition to procuring books from libraries, Google also obtains books from its publisher partners, through the "Partner Program" — designed to help publishers and authors promote their books. They can also choose to make the book fully viewable, and even allow users to download a PDF copy.
Books can also be made available for sale on Google Play. The publisher can choose to withdraw from the agreement at any time. For many books, Google Books displays the original page numbers.
However, Tim Parkswriting in The New York Review of Books innoted that Google had stopped providing page numbers for many recent publications likely the ones acquired through the Partner Program "presumably in alliance with the publishers, in order to force those of us who need to prepare footnotes to buy paper editions.
The project began in under the codename Project Ocean. Google co-founder Larry Page had always had an interest in digitizing books. When he and Marissa Mayer began experimenting with book scanning init took 40 minutes for them to digitize a page book. But soon after the technology had been developed to the extent that scanning operators could scan up to pages an hour.
Google established designated scanning centers to which books were transported by trucks. The stations could digitize at the rate of 1, pages per hour. The books were placed in a custom-built mechanical cradle that adjusted the book spine in place for the scanning.
An array of lights and optical instruments were used — including four cameras, two directed at each half of the book, and a range-finding LIDAR that overlaid a three-dimensional laser grid on the book's surface to capture the curvature of the paper.
A human operator would turn the pages by hand and operate the cameras through a foot pedal. The system was made efficient since there was no need to flatten the book pages or align them perfectly. The crude images were worked upon by de-warping algorithms that used the LIDAR data to process the images. Optical character recognition OCR software were developed to process the raw images to text. Algorithms were also created to extract page numbers, footnotes, illustrations and diagrams.
Many of the books are scanned using a customized Elphel camera   at a rate of 1, pages per hour. By constructing a 3D model of each page and then "de-warping" it, Google is able to present flat-looking pages without having to really make the pages flat, which requires the use of destructive methods such as unbinding or glass plates to individually flatten each page, which is inefficient for large scale scanning.
Each book on Google Books has an associated "About this book" page which displays analytical information regarding the book such as a word map of the most used words and phrases, a selection of pages, list of related books, list of scholarly articles and other books that cite the book, and tables of content. The list of related books can often contain irrelevant entries. Registered users logged in with their Google accounts can post reviews for books on this page. Google Books also displays reviews from Goodreads alongside these reviews.
For some books, Google also provides the ability to link directly to the front cover, title page, copyright page, table of contents, index, and back cover of a book, by using an appropriate parameter. For example, the front cover of a book with the OCLC number can be linked as books.
Signed-in users can create a personalized collection or a "library" of books, using the "My Library" feature. Organized through "bookshelves", books can be added to the library using a button that appears along with search results or from the "Overview" page of books.
The library can be shared with friends by making bookshelves publicly visible and sharing the private library URL. There are four default bookshelves which cannot be renamed: "Favorites", "Reading now", "To read" and "Have read". Users cannot add or remove books from these bookshelves.
The Ngram Viewer is a service connected to Google Books that graphs the frequency of word usage across their book collection. The service is important for historians and linguists as it can provide an inside look into human culture through word use throughout time periods. The project has received criticism that its stated aim of preserving orphaned and out-of-print works is at risk due to scanned data having errors and such problems not being solved.

Users can report errors in Google scanned books at support. The scanning process is subject to errors. For example, some pages may be unreadable, upside down, or in the wrong order.
Scholars have even reported crumpled pages, obscuring thumbs and fingers, and smeared or blurry images. Getting this right allows us to render the book in a way that follows the format of the original book. Despite our best efforts you may see spelling mistakes, garbage characters, extraneous images, or missing pages in this book.
Based on our estimates, these errors should not prevent you from enjoying the content of the book. The technical challenges of automatically constructing a perfect book are daunting, but we continue to make enhancements to our OCR and book structure extraction technologies.
Step 1: Add a new book
This method would only improve scanned words that are hard to recognize because of the scanning process and cannot solve errors such as turned pages or blocked words.
Scholars have frequently reported rampant errors in the metadata information on Google Books — including misattributed authors and erroneous dates of publication. Geoffrey Nunberga linguist researching on the changes in word usage over time noticed that a search for books published before and containing the word "internet" turned up an unlikely results. Woody Allen is mentioned in books ostensibly published before he was born.
Google responded to Nunberg by blaming the bulk of errors on the outside contractors. Other metadata errors reported include publication dates before the author's birth e. A review of the author, title, publisher, and publication year metadata elements for randomly selected Google Books records was undertaken.

This error rate is higher than one would expect to find in a typical library online catalog. The overall error rate of While "major" and "minor" errors are a subjective distinction based on the somewhat indeterminate concept of "findability", the errors found in the four metadata elements examined in this study should all be considered major. Metadata errors based on incorrect scanned dates makes research using the Google Books Project database difficult.
Google has shown only limited interest in cleaning up these errors. Some European politicians and intellectuals have criticized Google's effort on linguistic imperialism grounds. They argue that because the vast majority of books proposed to be scanned are in English, it will result in disproportionate representation of natural languages in the digital world.
German, Russian, French, and Spanish, for instance, are popular languages in scholarship. The disproportionate online emphasis on English, however, could shape access to historical scholarship, and, ultimately, the growth and direction of future scholarship.
While Google Books has digitized large numbers of journal back issues, its scans do not include the metadata required for identifying specific articles in specific issues.
This has led the makers of Google Scholar to start their own program to digitize and host older journal articles in agreement with their publishers. The Google Books Library Project is aimed at scanning and making searchable the collections of several major research libraries. If a book is out of copyright and in the public domain, the book is fully available to read or download.
In-copyright books scanned through the Library Project are made available on Google Books for snippet view. Regarding the quality of scans, Google acknowledges that they are "not always of sufficiently high quality" to be offered for sale on Google Play. Also, because of supposed technical constraints, Google does not replace scans with higher quality versions that may be provided by the publishers. The project is the subject of the Authors Guild v.
Google lawsuit, filed in and ruled in favor of Google inand again, on appeal, in Copyright owners can claim the rights for a scanned book and make it available for preview or full view by "transferring" it to their Partner Program accountor request Google to prevent the book text from being searched.
The number of institutions participating in the Library Project has grown since its inception.
Other institutional partners have joined the project since the partnership was first announced: . The history page on the Google Books website describes their initial vision for this project: "in a future world in which vast collections of books are digitized, people would use a ' web crawler ' to index the books' content and analyze the connections between them, determining any given book's relevance and usefulness by tracking the number and quality of citations from other books. In a conversation with the at that time University President Mary Sue Colemanwhen Page found out that the University's current estimate for scanning all the library's volumes was 1, years, Page reportedly told Coleman that he "believes Google can help make it happen in six.
The announcement soon triggered controversy, as publisher and author associations challenged Google's plans to digitize, not just books in the public domain, but also titles still under copyright.
September—October : Two lawsuits against Google charge that the company has not respected copyrights and has failed to properly compensate authors and publishers.
One is a class action suit on behalf of authors Authors Guild v. Google, Sept. McGraw Hill v. GoogleOct. It also added a new browsing interface along with new "About this Book" pages.
