I found the book to be a great source of information concerning observatories all over the world. She provides a lot of information about the instruments and history of how and why they were constructed, what sorts of things the instruments were designed to observe, how much data they are gathering or plan to gather, and more.
I liked the chapter 7 on Observatories of the Future. It was a little more readable than the other chapters. As a Denver person, I am glad that she mentioned two DU observatories. They were historic Chamberlin Observatory on page 107 and the Meyer-Womble Observatory on page 213. She misspelled Chamberlin as Chamberlain.
She did have several other typos, such as confusing Purdue University using the word Perdue instead. I also feel that the book really could have used an index. For example, if I wanted to see what sections of the book covered observatories in Chile, I would have to search the whole book. If it had an index, I would be able to see what pages covered the large number of observatories in Chile.
Overall, I really liked the book. Now I may have to find some of the other books that she has written.
