(1) The author wishes to submit his material to his associates or to specialists in the field. Except for purposes of proof-reading such submission should be made in manuscript.
(2) The author fails to return his proofs and manuscript copy promptly. The prompt reading and return of proofs is of the greatest importance.
(3) The copy for the index does not follow closely upon the return of the final batch of page proofs.
The printer, the engraver, the paper manufacturer, the binder or the publisher may also interfere with prompt publication; but if the author's end of the work is handled systematically and promptly, we are generally able to control the manufacturing details.
Transcriber's Note
Sundry missing or damaged punctuation has been repaired.
Page 6, etc.: 'sub-headings', and 'subheadings' both appear in this book, as do 'proof-reader' and 'proofreader', and some other instances of hyphenated and non-hyphenated words.
As it is a book of suggestions on layout and style from a respected publishing house, it can be assumed they knew what they intended, so both hyphenated and non-hyphenated words have been retained.
