Colorado, 1870-2000 
The contrast between Jackson's and Fielder's photographs not only illuminates Colorado's past but will help us determine the course of land management as we move into the next century. Accompanied by an educational program that includes lectures, a traveling exhibit, newspaper serialization, and television series, this book is aimed at encouraging people to appreciate and reflect on nature, history, and photography as we move into the next century. Colorado: 1870-2000 stands not only as an important document of westward exploration, expansion, and urbanization, but helps define our past and future environmental values.
Reviews
On the other hand, the text is a different story. Reading a text-only version of this book, one might conclude that the title is a misprint, and that the book should really be called "Colorado 1970 - 2000." Fielder roamed across Colorado capturing the changes in places like Kremmling, Denver, and Ouray, but the text never tells us anything about these places, or why they changed, or why we should care. Instead we get chapters about oil shale and the Forest Service.
Ahem. If I wanted to read about the relationship between Forest Service bureaucrats and small Western towns, I would have bought a book called "The Relationship Between the Forest Service and Small Western Towns." My book is called "Colorado 1870 - 2000." That is what I want to read about.
It's true that oil shale schemes, government agencies, and others have played a role in shaping Colorado in the past 30 years. But before that there were events like the Silver Crash of 1893, the City Beautiful movement, the Depression, World War II, and Urban Renewal. You won't read about those in this book.
The pictures are beautiful, and the text is well-written (if misplaced and unwanted). Just don't expect to learn much about the places you are looking at- except that they are very pretty.
1) Accuracy of Photo Retakes: While Fielder did a rather competent job of matching the historic photos, Collier did a remarkable job. Unless it was impossible to match them, due to trees blocking the view, etc., most of Collier's photos appear to be taken from nearly the exact location as the historic photos. EDGE: Colorado: Yesterday & Today.
2) Originality: Since both of the books were published within a short time span, it seems possible that one photographer copied the other's idea for the book. Initially, I assumed that Fielder started on his book first. But, after looking into it, I was surprised to find that Collier started working on his book before Fielder even decided to do his book. EDGE: Colorado: Yesterday & Today
3) Reputation: This is Collier's first book, while Fielder has published many other books. EDGE: Colorado: 1870-2000
4) Written Text: Colorado: 1870-2000 has some interesting essays written by leading environmentalists, historians, etc. My one complaint is that the essays do not really provide any information on the photos in the book. Colorado: Yesterday & Today was written entirely by the photographer, Grant Collier. He did a very competent job writing the histories of the towns in the book, and this text provides the reader with additional information on the photographs in the book. EDGE: EVEN
5) Appearance of the book: Colorado: 1870-2000 is a very large book and is perhaps a little bulky. But the large photos in it are quite nice. Colorado: Yesterday & Today is more of a standard size book, and it is easier to sit down and look through this book. But the photos are obviously not quite as large. Also, both books have VERY NICE leather covers. EDGE: EVEN
6) Intangibles: In Colorado: 1870-2000 Fielder reshot the images of pioneer photographer William Henry Jackson. In Colorado: Yesterday & Today Collier reshot the images of his great-great-grandfather, and pioneer photographer, Joseph Collier. This adds a fascinating human-interest aspect to Colorado: Yesterday & Today that is lacking in Colorado: 1870-2000. EDGE: Colorado: Yesterday & Today.
OVERALL VALUE: The SRP of Fielder's book is $95, while the SRP of Collier's book is $39.95. So, given the price and quality of Colorado: Yesterday & Today, I would say that it is certainly the best overall value.
To conclude, if you're only going to buy one Colorado "then and now" book, I'd recommend Colorado: Yesterday & Today. If you're going to buy two, Colorado: 1870-2000 isn't too bad a buy, either.
