Electronic manuscripts are content tagged to identify all elements in your manuscript. Do not format your manuscript with standard word processing functions-use content tags to identify manuscript elements.
	Many manuscripts are converted from one word processing program to another, and any formatting (e.g., boldface, caps, ital) may be lost in conversion; content tags allow the copyeditor to identify the structure of the manuscript.
	Content tags should be placed before and after each section.
