Photo and Graphic Credits
The visuals, especially the photos, are one of the things that make this book what it is. As of September 2020, the book contains 1028 figures; almost all are full color and most are photographs. And, the majority of the photos came from Wikimedia Commons or others websites where selfless individuals have made their material available under a Creative Commons license for educational purposes. We have put figure credits at the end of every chapter. But, a number of individuals deserve special recognition for all the terrific photos they have shared: James St. John, Didier Descouens, Robert M. Lavinsky, Géry Parent, Marie Lan Taÿ Pamart, Siim Sepp, Andrew Silver, Eurico Zimbres, Amcyrus2012, Alex Strekeisen, Chmee2, Kevin Walsh, Teravolt, Acroterion, Amotoki, Bereket Haileab, Brocken Inaglory, Daniel Mayer, Graeme Churchard, Jan Helebrant, John Krygier, Kelly Nash, Leon Hupperichs, Mike Norton, R. Weller, Raike, Roy Goldberg, Walter Siegmund, and Woudloper. Unbeknownst to them, every one of these individuals contributed multiple photos to this project.

Ongoing Project
The nature of this kind of book means that it is always an ongoing project. As of fall 2020, the beta versions of the first 13 chapters are completed. They are being reviewed and edited. We are actively adding links to videos and other web resources. And we have just begun a mineral encyclopedia that will contain the standard sorts of descriptions of minerals, along with many photographs and drawings, that are found in the back of all mineralogy books.

Web Browsers
Different web browsers have different quirks. For the best and most consistent results, we recommend using Chrome and recommend against using Firefox when viewing this book. But, sometimes Chrome does not show the same sharp images that Firefox does. So, the bottom line is that you should try several browsers and use the one that works best for you. They will NOT be the same. Additionally, we warn that many tables will not render well on small screens, and not at all on cell phones.
