Abstract
This paper presents a general view of communication, and urges those who write on technical subjects to follow the `rules' in existing books of instruction. Expediency and custom are the basis of these most acceptable ways for presenting written and spoken messages of many kinds. Such suggestions can be very helpful for writers who want to communicate technical matters successfully. By following the recommendations given in guides like the seven listed in this paper, the author of a technical article is likely to please those who think form and correctness are important, to impress those who think nothing is important, and to be understood by all.
