Another major difference is that they usually don't want a header showing the title, author's last name, and the page number since that would be copied along with the rest of the manuscript and make the overall page numbering task difficult for the publisher. When in doubt, ask the publisher using this method about those. As well, they don't want a blank line between paragraphs unless it's to denote a major change of scene or time within a chapter. Using lines with asterisks to separate changes of scene or time also appear to be acceptable in this format. Again, ask the publisher when in doubt.
Electronic formats are yet another nightmare for both the writer and publisher.
As with the print formats, certain information must be provided to the publisher so that the publisher will know who to contact once the submission has been read. After all, you don't want to be rejected because you forgot to tell the publisher how to contact you. However, the writer must be aware to begin with that some features are strictly forbidden as they cause more than their share of grief for everyone. Many publishers will not accept submissions with problems such as those caused by smart quotes so the writer is well advised to turn that feature off in the writer's own choice of word processor. As well, italics and other features often don't convert.
