Abstract:

Teachers often emphasize the importance of the 'three Rs'--reading, 'riting, and 'rithmetic. For people who earn a living through writing, as well as for those whose writing is a pastime, a solid grasp of the first two R's is indispensable. There is, however, a fourth 'R' critical for writers--research.
