Do you have a copy of the 2002 Writer's Market (http://www.amazon.com/exec/obidos/ASIN/1582970440/ref=pd_sim_books/002-0682736-5043241), or the Writer's Guide to Book Editors... (http://www.amazon.com/exec/obidos/ASIN/0761530231/qid=1020461606/sr=2-1/ref=sr_2_1/002-0682736-5043241), yet? I gather they're helpful.
