Quality & Value,
This review is from: Iguanas For Dummies (Paperback)Living in the Florida Keys we have dealt extensively with discarded Iguanas - perhaps 15 or more. People buy them, and get rid of them constantly - and down here, in the semi-tropics, they can survive (with difficulty)in the wild.
With all the iguana problems we have encountered good information is a necessity, & we have purchased many iguana books including Hatfield's "Green Iguana, the Ultimate Owners Guide" (a great book, but we still prefer Kaplan's "Iguanas for Dummies").
If you still want addtional technical data you can add "What's Wrong with My Iguana" by John Rossi M.A., D.V.M. and "Understanding Reptile Parasites" by Roger Klingenberg D.V.M.
Kaplan's book is based on research & a lot of personal experience. It is thorough, and her experience shows through - there are tidbits of information that have been useful to us that we have not found elsewhere. She has long maintained a caring website to help iguana owners and potential iguana buyers - not just to sell books. And the price of this book is reasonable.
By all means get a good book like Hatfield's or Kaplan's - preferably before you get an iguana. Even if the book talks you out of getting an ig for a pet it will be well worth the price. Proper care for an iguana involves a devoting a lot of time and spending a lot of money. The cost of the animal is nothing in comparison, and they are far more complex to care for than a dog, cat, or hamster. Judging from the number of abandoned iguanas in the Florida Keys a huge number of people do not bother to inform themselves and the animals suffer. It may not be entirely their fault. Many pet stores do not seem to offer the best books or accurate information - often they just want to sell a hapless reptile, and make a few bucks on inadequate (sometimes dangerous) supplies and food. They frequently give bad advice.
Whatever book you get you will still need to get a good experienced herp vet., and they are hard to find. Things go wrong with iguanas that are not covered with specificity in any of these books. We have been unfortunate enough to encounter some of them.
