3 comments about Mineral Collector's Handbook.

1. Well, it's a nice book and all, but Mr. Krause has lost all objectivity in discussing the various minerals of the world. I was surprised that he completely overlooked gypsum--certainly one of the most useful minerals around (plaster products, fertilizer). Perhaps the author should spend less time using a thesaurus (trying to impress us?) and more time studying minerals and rocks



2. I have only recently begun to collect various minerals. I couldn't disagree more with this other reviewer. I found it to be very thorough, easy to understand, and helped me immediately in categorizing my collection. Well worth the price, and an invaluable reference book for years to come.



3. I found this book to be extremly helpful with my research. The numerous color photos are a real plus. I'd highly recommend this title.

2 comments about Dinosaur Collectibles.

1. Being a dinosaur collector, I found this book interesting and quite comprehensive. Full of pictures and good quality printing! Though there are still rooms for improvement. For example, the list of the Carnegie collection is not complete, neither is that of the Jurassic Park series. The prices contained for some of the items are not realistic, too. Despite the above, I still love this book very much. Thank you!



2. Any collector of dino toys/models/replicas simply MUST HAVE THIS BOOK! As well as being a fountain of info of interest to the collector it is wonderful for just browsing through. Mike Fredericks and Dana Cain have done dino lovers everywhere a wonderful favor by producing this wonderful, long overdue book. (A big tip of the cap also to "Big-Time Dino Collector Par Excellence" Dean Walker who supplied copious amounts of beautiful photos). If you love dinos and you don't have this book, you my friend are living a lie!

5 comments about Jade.

1. Jade, by Roger Keverne, is a complete review of all the jades, all the deposits, all the mines, the history, (and with jade this is a long one.) the lore, the geology. Jade features a collection of articles by contributors from around the world, most members of the FRIENDS OF JADE, and all experts in their fields. Whenever I need to seek an answer, a representative photo, in short, anything in jade, here it is, in one book. If you are interested in jade, to sort out the truth from the rumors, the real from the fake..... this is THE jade book.



2. Extremely great book on the subject of jade. Book even includes the very rare today "Wyoming Jade"...should be a book devoted to that subject.



3. From this heavy tome, you will learn how artists "let the jade speak to them" before carving wondrous works of art. The properties of jade are perfect for carving because its molecular structure is tightly bound. Jade can suffer great detail in carving without cracking or chipping.

   Jade is either nephrite or jadeite. Cheaper substitutes are bowenite and serpentine, so the buyer must beware.

   Keverne takes us on a jade "trip around the world" from the Pacific Rim to Mesoamerica. The latter finds are a great mystery, because no known source of jade in Central America is currently known to exist. The photographs in this book are tightly focused and glowing. Keverne continually displays his expertise in his subject. He includes an excellent index and bibliography. Like David Grimaldi's thorough book on amber (Amber: Window to the Past), this book is the authority on the subject of jade.

5. I study Jade Culture of the Orient and I use this reference for the good bibliography, and illustrations. It is an attempt by the now defunct 'Friends of Jade Society' to compile a comprehensive reference on jade and ancient and historical jade cultures from all over the world. For most of the world it is reasonably accurate, but unfortunately the Chinese section concerning jade has more errors than a freshman essay. This is even more embarrasing since most of the book is devoted to Chinese jade culture. A more detailed list and discussion of these errors and problems is available upon request.

5 comments about Dinosaur Lives: Unearthing an Evolutionary Saga.

1. Touches on lots of topics: various dinosaurs, bone sites, evolution, extinction, digs, past and present bone hunters, the science of the Jurassic Park movie, etc. Very easy to read.



2. To the publisher I would appreciate it if the publisher could produce an audio adaptation of this book. I would love to listen to this while I drive to work and to let my 16 month old son listen to it as a bedtime story. My goal is to expose him to some of my favorite passions, maths, sciences, physics, geophysics, paleontology, astronomy, electronics, photonics, new science and discoveries etc. The more audio books you can produce of the above genre the more I will support you.

3. Mr. Horner has made an extraordinary accomplishment with 'Diggin Dinosaurs,' as it is able to present relative information regarding the topic at hand in a manner to be easily read by the masses and hold the reader's attention. His ability to stimulate the imagination with his illustrative speach and diction is quite amazing, as is his ability to distill the necessary information from the vast amounts of data that is available for analysis. An amazing breakthrough to be certain.



4. Dinosaur Lives introduces the lay reader (that would be you and me) to a number of exciting ideas. The book provides us with an update to Horner's field work since he wrote "Digging Dinosaurs," but it also delves deeper into some of the bigger ideas concerning dinosaurs. A large portion of the book is devoted to speculation about the behavior of dinosaurs, especially the raising of young and herd/pack associations. What interested me most, however, is Horner's deconstruction of Linnean taxonomy, and the description of cladistics as a more powerful tool to look at relationships between living and extinct creatures. For those of us raised on the idea of speciation, this is powerful stuff. You may find, as I did, that light bulbs start popping in your head as you realize that the very way you think about a subject can severely limit your ability to perceive new ideas.

   If all this sounds a bit airy-fairy, Horner does a much better job than I can here explaining some pretty complex stuff in a very simple way. My only complaints about the book are that Horner sometimes can be a bit wordy while telling us what he is about to tell us. I could have used a bit more technical detail in some of his descriptions, and certainly the illustrations should have been more complete. These are minor complaints, however. This is a fascinating book for anyone who likes thinking about dinosaurs, and the endless cycles of life. You don't need to have any prior knowledge to thoroughly enjoy this book.




5. Dinosaur Lives: Unearthing an Evolutionary Saga written by John R. Horner is a well-written account of paleontological fieldwork told in an engaging style. This book is the continuation of the book Digging Dinosaurs one of the author's previous books.

   Horner is a thinker as has helped out on numerous motion pictures to make the dinosaurs seem real and alive. In this book we get to read (speculation) about dinosaur eggs, their young and their nests as found from the fossil record.

   Horner has an infectous style when he write and you can't help but getting into lock-step with him as he writes a telling-tale, making the read feel as if you are there right along side. Our understanding of how dinosaurs grew up, raised their young, and socialized with other dinosaurs are brought out in this book.

   There is still a lot of information yet to be discovered, but Horner has been making long strides in elucidating information and answering some of the nagging questions involving dinosaurs. Some of the new evidence and arguments regarding the major dinosaur controversies of the day, being that of warm-blooded verses cold-blooded are tackled in this book.

   This book is a quick read and should be on your bookshelf as the author's discoveries regarding the dinosaur are ground-breaking and unparalleled. Paleontologist Robert Bakker is another forward thinker when it comes to dinosaurs.

   This book gives some credence to Bakker's theory about the inland sea retreats and the dinosaurs from the eastern part of the North American continent mixed with those of the West, exchanging bacteria and other pathogens for which the recieving group had no inherent resistance. This could be a slow death or a prolonged one depending upon the pathogen involved. Also, climate was changing substantially at that time as well, becoming cooler, and more arid, this could slowly add to the demise of the dinosaurs.

   This book was an enjoyable, engaging read.

5 comments about The National Gem Collection.

1. If you have visited the National Collection and want a souvenir to remind you of the stunning array of unique World Class Gems then this is the book for you. Both the format of the book and the superlative quality of the photography make this book the next best thing to being in the exhibition hall. There is a fairly light weight coverage of the gemmology in the text, but it mostly focusses on the history and ownership of these fabulous gems. The National Collection is unique, no where else in the world is there such a concentration of fabulous jewels with such an interesting history, with the possible exception of the British Crown Jewels in the Tower of London. This book is a fitting celebration of such a marvellous collection.



2. This is a beautiful book with lots of interesting information on the gem collection.



3. "The National Gem Collection," by Jeffrey E. Post, features photographs by Chip Clark. The book is a beautiful celebration of the title collection, which is part of the Smithsonian Institution. The informative text discusses the history of the collection, facts about types of different gemstones, and specific pieces in the collection.

   The full-color photography is really stunning, and brings a rich assortment of gems to glorious life. Some of the historic pieces pictured are the blue Hope Diamond, the diamond Napoleon Necklace, the Hooker Emerald, and more. Also shown are a colorful collection of "fancy" diamonds, a rare red diamond, the 858-carat uncut Gachala Emerald, the delightful "pink tutu" (a band of dainty rose quartz crystals on a large smoky quartz crystal), a dazzling group of fire opals, a lapis lazuli carving from Afghanistan, and more.

   I appreciate how the book celebrates gemstones at various stages: uncut, cut, and set in artfully crafted pieces of jewelry. Many different types of gemstones--aquamarine, garnet, spinel, chrysoberyl, turquoise, etc.--are covered. Features such as a scanning electron microscope photo of the inner structure of an opal give the reader a deeper understanding of the science behind gems. From start to finish, this book is a marvelous feast for both the eyes and the brain.




4. This review is for the paperback version of the book, which I loved. It has a lovely balance of terrific photos & explanations of the various sources of the featured gems. It serves as a nice beginning reference when you have heard the terms sapphire & red sapphire (huh? I thought red gems were rubys or spinels) and would like to know more about which gems are related to others.
   
   And did I say the photos are just wonderful? Enjoy!



5. Excellent information on the history of gemstones, understanding color and cuts. Exquisite examples, beautifully photographed. A must for anyone interested in gemstones or the history of jewelry.
