Q. Can you help me find good information for the controversy with stem cells?

I think we can help.

a). We also have a two volume encyclopedia of stem cell research in our reference collection [Ref. QH588 .S83 E53 2008]. You could use it to address specific "technical" questions about stem cell research.

b).  You could also do a search for stem cells in Reference Universe - http://libguides.css.edu/az.php?a=r

In particular, it will give you access to Bioethics, a multi-volume encyclopedia of medical ethics. It will give you some insight into the ethic aspect, which I think would be the toughest sell you would have in your presentation.

I hope this is enough to get you started.
