When Editing & Formatting a document for books, there are a few things to keep in mind. First, you will want to make sure that your document is in a font that is easy to read. Times New Roman or Arial are both good options. You will also want to make sure that your margins are at least 1 inch on all sides, and that your text is double-spaced. Finally, you will want to include a header at the top of each page that includes the title of your book and your name. Professional document formatting services take care of this process.
