Lit review con't

Gee, who would have thought I'd be doing homework on Thanksgiving?

I believe that one of the hardest things about conducting a lit review is knowing when to stop collecting literature! Each new lead looks interesting, something more to add to the bookshelf...but I have to stop and finish writing the review at some point...I sure hope it's what the dept. is looking for - since I've not written one of these before, I suppose I'll have to write it the way I'd like to read it (most likely, not the "proper" way of doing this...sigh).
