I just got my second issue of the Iguana Times the journal of the International Iguana Society. It is an excellent publication! It covers a variety of topics husbandry, zoo management, and it's heavy on conservation articles. There seems to be a lot of Cyclura in this publication but other Iguanids are cover including the once Iguanids such as the anoles and curly-tails (They have been moved to their own families.).
The only drawback is that it is quarterly. I have to wait 3 months for the next issue!
I highly recomend this to anyone with a serious interst in these critters. I signed up on their website.
