Where can I find information on the family Phascolarctidae and genus Phascolarctos?

I'm writing a paper and I need information on the family Phascolarctidae and genus Phascolarctos. I can't find very much information on that family and genus. I need to write atleast three fourths of a page on each of those. Where can I find information on them? (Preferably reliable sources on the Internet.) Thank you.Where can I find information on the family Phascolarctidae and genus Phascolarctos?Here are two good, reliable online places with information on koalas:
The Animal Diversity Web: http://animaldiversity.ummz.umich.edu/si鈥?/a>

and this is a book published by the Australian Government, you can download the chapters about marsupial mammals in general or the one about the koalas in particular. This is the home page: http://www.environment.gov.au/biodiversi鈥?/a>
and here's the link for the Phascolarctidae (it's a pdf): http://www.environment.gov.au/biodiversi鈥?/a>

Interesting bit of trivia that you can include in your paper: Did you know that their scientific name means "grey pouched bear"? From the Greek and Latin roots: "Phascol" = pouched + "arctos" = bear + "cinereus"= ashy-grey

Good luck with your paper!
