Publisher's Tips
Be sure to scan your photos at 300 dpi grayscale (if printing in black and white) and save as TIFF for publication.
Line art and illustrations should be scanned between 600 and 1200 dpi and saved as TIFF.
Invest in The Chicago Manual of Style, 16th Edition (Chicago: The University of Chicago Press, 2010) for the best advice on manuscript preparation. This fine publication should answer all your questions concerning style and the extensive bibliography will lead you to other publications for your particular writing genre.
