Kim Tracy (tracy@ihspa.att.com) endorses last week's book-publishing tips, but would further emphasize a marketing orientation. Learn the language of marketing to describe the specific market for your book. (Publishers can be persuaded by competent market studies, and they seek long-term relationships with authors who write for profitable markets.) Know what makes your book unique, what will make people buy it, and how many such people the publisher can reach with advertising. Larger publishers may be uninterested in sales of less than 20K copies. Beware of publishers who will keep you hanging for eighteen months; if you can't get a firm commitment, try another publisher.
