There are several keys to being published. First is the quality of your writing. The second key requirement for being published is having a book that is marketable. Third, you must create a terrific book-publishing proposal. Fourth, you must know the difference between traditional (trade) publishers and POD, vanity and other forms of self-publishing. Beware of scam-artists. Fifth, be prepared to contact hundreds of smaller trade publishers that focus on your particular genre. Fifth, create a killer e-mail cover page that will demand the attention of the publisher or agent. Sixth, be ready to create web site proposals for publishers that won't open attachments. Seventh, never accept the first offer, unless it's the best offer.
