Assert your judgment fairly and with respect. Know why you are choosing to publish something. Not only is this vital for a strong editorial mission, but it will also help you market and promote the magazine or title. Editing and publishing good literature is only half of your responsibility. You also have an obligation, to your writers and to your mission, to distribute and promote your magazine or titles to your potential readers.
Visibility is very important to a new press or magazine which is just creating a name for itself.
Apply for prizes, submit titles or issues for review, develop your local media contacts. All these efforts will help your name recognition. An important part of publishing is attending readings and circulating among writers, making contact with new ones, and keeping the magazine or press in people's minds. Authors that will work hard for their books by doing readings and outreach are invaluable. Establish a consistent, standard operating procedure so that you don't have to publish, promote and sell each book or issue as if it were the first.
