Have you included the address for correspondence? Is the abstract formatted exactly as required? Is the style of references correct? Are the tables and figures correctly numbered? You are usually required to provide each on a separate page. You should ensure that you have indicated in the margin where they should appear when the paper is typeset. Is all artwork correctly prepared? Are the pages numbered consecutively (1,2,3 ...)? Have you produced enough copies of the manuscript, tables and figures? You are usually required to send between three and five copies.
