This library is built in the open.
If you spot an error, have a suggestion, or just want to say hello — we’d love to hear from you.

A woodcut depicts the Google logo in its characteristic multi-colored font.
This is a digital copy of a book that has been kept on library shelves for generations before being carefully scanned by Google as part of a project to make the world's books available online.
The book has outlived its copyright and can now be made publicly accessible. A publicly accessible book is one that was never subject to copyright or for which the copyright term has expired. Whether a book is publicly accessible may vary from country to country. Publicly accessible books are our gateway to the past and represent a historical, cultural, and scientific treasure that is often difficult to discover.
Signs of use, annotations, and other marginal notes contained in the original volume are also found in this file; they serve as a reminder of the long journey the book took from the publisher to a library and on to you.
Google is proud to partner with libraries to digitize publicly accessible material and make it available to the general public. Publicly accessible books belong to the public, and we are merely their guardians. Nevertheless, this work is costly. To continue providing this resource, we have taken steps to prevent abuse by commercial parties. These include technical restrictions on automated queries.
We ask that you adhere to the following guidelines:
Use of files for non-commercial purposes We designed Google Book Search for end-users and ask that you use these files only for personal, non-commercial purposes.
No automated queries Do not send automated queries of any kind to the Google system. If you are conducting research on machine translation, optical character recognition, or other areas where access to text in large quantities is useful, please contact us. We encourage the use of publicly accessible material for these purposes and may be able to assist you.
Maintain Google brand elements The Google "watermark" you find in every file is important for information about this project and helps users find further material via Google Book Search. Please do not remove the watermark.
Stay within the law Regardless of your intended use, you must be aware of your responsibility to ensure your use is legal. Do not assume that a book that we believe is publicly accessible for users in the USA is also publicly accessible for users in other countries. Whether a book is still subject to copyright varies from country to country. We cannot provide advice on whether a specific use of a specific book is legally permitted. Do not assume that the appearance of a book in Google Book Search means it can be used in any form anywhere in the world. Copyright infringement can have serious consequences.
Google's goal is to organize the world's information and make it generally useful and accessible. Google Book Search helps readers discover the world's books and supports authors and publishers in reaching new audiences.
