This library is built in the open.

This is a digital copy of a work that has been preserved for generations on library shelves before being carefully digitized by Google as part of a project to make the world's literary heritage discoverable online.
Since this book is relatively old, it is no longer protected by copyright law and now belongs to the public domain. The expression "to belong to the public domain" means that the book in question has never been subject to copyright or that its legal rights have expired. The conditions required for a book to fall into the public domain can vary from one country to another. Public domain books are links to the past. They are witnesses to the richness of our history, our cultural heritage, and human knowledge, and are too often difficult for the public to access.
Footnotes and other annotations in the margins of the text present in the original volume are included in this file, as a reminder of the long journey traveled by the work from the publishing house, through the library, to finally find itself in your hands.
Google is proud to work in partnership with libraries to digitize works belonging to the public domain and to make them accessible to everyone. These books are, in fact, the property of all, and we are simply the guardians of this heritage. However, this is a costly project. Consequently, and in order to continue the dissemination of these inexhaustible resources, we have taken the necessary measures to prevent any potential abuse by third-party commercial sites, particularly by establishing technical constraints regarding automated requests.
We also ask that you:
Do not use the files for commercial purposes We designed the Google Book Search program for individual use. We therefore ask that you use these files only for personal purposes. They cannot be used for any commercial purpose.
Do not perform automated requests Do not send any automated requests of any kind to the Google system. If you are conducting research concerning translation software, optical character recognition, or any other field requiring the use of large quantities of text, do not hesitate to contact us. We encourage the use of works and documents belonging to the public domain for this type of work and would be happy to be of service to you.
Do not remove the attribution The Google watermark contained in each file is essential to inform internet users about our project and to allow them to access more documents through the Google Book Search program. Do not remove it under any circumstances.
Remain within the law Whatever use you intend to make of the files, do not forget that it is your responsibility to ensure compliance with the law. If a work belongs to the American public domain, do not assume that the same applies in other countries. The legal duration of a book's copyright varies from one country to another. We are therefore not in a position to list which works are authorized for use and which are not. Do not believe that the simple fact that a book is displayed on Google Book Search means that it can be used in any way, anywhere in the world. The penalty you would face in the event of copyright infringement can be severe.
By promoting research and access to an increasing number of books available in many languages, including French, Google wishes to contribute to promoting cultural diversity through Google Book Search. Indeed, the Google Book Search program allows internet users to discover the world's literary heritage, while helping authors and publishers expand their audience.
