Created twice, Elaine Pagels, and some help from you

I had a debate last night and now can't for the life of me find a resource that I like to peg to either side. Can you help?

The meat of it is this: there are two different creation story frames in Genesis, one taking place mostly in Chapter 1 and the other in parts of Chapter 2. The order if events is different, as are the tone and conclusion of each story. Either this is significant, from the perspective of belief, or it is not a big deal, so went the conversation.

Elaine Pagels has plenty to say in her books (specifically Adam, Eve, and the Serpent) and so, interestingly enough, does Wikipedia (see here). However, I was surprised at how few credible, academic treatments I could find on either side in a couple of Google searches.

I need to burrow into the library databases now, but I would prefer to link to something everyone can see, access, and debate.
