That is the best captive husbandry lizard book in print, really a well done piece. It is out of print, has been for some time. Mampam is Dan Bennett, one of the authors. We also have a handful of copies still for sale.
I have tried to convince Daniel to make it an e-book, since a second printing is expensive, but I don't know that the logistics will work for that.
Every lizard keeper should have this book though, regardless of species. Great captive husbandry is similar across most lizard species. Uros, Beardeds, monitors, tegus, this book has great husbandry info to apply to all of them.
