Type on one side of the paper only. All margins should be at least one inch and not more than one and a half inches. Do not bind your manuscript in any way, except with a paper clip. When in doubt, write a short letter to the publisher first to find out their submission guidelines. Unless the manuscript is specifically for a book publisher, type each story separately and do not number the pages in sequence except for individual stories.
Photocopies are okay only if they are excellent reproductions.
Manuscripts must be easy to read, clean and clear. Check with the publisher before sending simultaneous submissions. Many publishers do not accept them. If you send a simultaneous submission, mention it in your cover letter. Try to limit simultaneous submission to publishers whose circulations do not overlap.
