DIGITAL BOOKS


There have been several projects to digitize older books that are no longer subject to copyright. Google is the predominant leader in the effort to digitize entire libraries. Fortunately, these books include many old geology and mineralogy books. Unfortunately, they are digitized by students and contractors who are not familiar with the geologic literature and give the digital files incorrect, misleading, or cryptic names. This makes some digital reference books extremely difficult to locate, and it takes a lot of digging to find them. I have done the digging for you!

This is truly amazing! An entire digital library at your fingertips! All books are in PDF format. I have included the file size in the link so that you will know how large the file is and how long it will take to download.

A few words from Google...

These books have survived long enough for the copyright to expire and the book to enter the public domain. A public domain book is one that was never subject to copyright or whose legal copyright term has expired. Whether a book is in the public domain may vary country to country. Public domain books are our gateways to the past, representing a wealth of history, culture and knowledge that is often difficult to discover.

Marks, notations and other marginalia present in the original volume will appear in this file - a reminder of this book's long journey from the publisher to a library and finally to you.

Usage guidelines

Public domain books belong to the public and we are merely their custodians. Nevertheless, this work is expensive, so in order to keep providing this resource, Google has taken steps to prevent abuse by commercial parties, including placing technical restrictions on automated querying. Google also ask that you:

Make non-commercial use of the files. We request that you use these files for personal, non-commercial purposes.

Maintain attribution. The Google watermark you see on each book scanned by Google is essential for informing people about this project and helping them find additional materials through Google Book Search. Please do not remove it.

Keep it legal. Whatever your use, remember that you are responsible for ensuring that what you are doing is legal. Do not assume that just because Google believes a book is in the public domain for users in the United States, that the work is also in the public domain for users in other countries. Whether a book is still in copyright varies from country to country. Please do not assume that a book scanned by Google means it can be used in any manner anywhere in the world. Copyright infringement liability can be quite severe.
