Standard Manuscript Format
When you are submitting a manuscript to a publisher or for an anthology the editor is going to give you specific requirements so that your manuscript will even be considered. If there are no specific requirements listed or you aren’t sure what the Standard Manuscript Format is, you should use the Shunn Format. William Shunn has based this format on what publishers and publications have used for decades.
