first pass pages
a mock up of your book’s pages that you will look over for any mistakes
When will I get my first pass pages?
After you finish copy edits. You’ll be given a few to several days to look them over and note any typos or small mistakes. At this point, it is too late to make large changes to your manuscript that will affect the layout of your book. If your editor does not ask for you input on the first pass pages beyond telling you which mistakes the proof reader found, offer up your input anyway. You will almost certainly find mistakes that no one else finds and you don’t want those going to print.
