In one form or another, this is probably the most asked question on the
newsgroup.  There are at least three iguana care sheets readily
available
on the Web, and plenty of peripheral documents.  A good central resource
for iguana information is Liza Daly's iguana page:
        <http://fovea.retina.net/~gecko/herps/iguanas/index.shtml>
which includes pointers to lots of documents.

This page also includes some information on the iguana mailing list.  To

It really is worth your while to read these care sheets before posting
an
iguana-related question.  There are a *lot* of pet iguanas out in the
world,
and much discussion of them on the net, and the chances that your
question has
already been asked and answered are pretty good.

There are many books on iguanas; most of them aren't very good, and
iguana
keepers on the net say that none of them are really good enough to
recommend.
As of early 1996, there are more books in the works that show some
promise;
however, the online care sheets remain the iguana keeper's strongest
resource
for the present.
