Maintaining a style sheet can help you keep track of special spelling, terminology, punctuation, capitalization, and other word or formatting usage.
A style sheet is the place where you and the editor can log the decisions made about product names, numbers, abbreviations and acronyms, hyphenation, and capitalization. If the document you are writing or editing is part of a set, using a style sheet helps maintain consistency among the various books.
When you create a style sheet, remember to pass it on to others who may benefit from it - writers of related documents, editors, illustrators, and production specialists.
