Jerome Perlmutter writes here out of his experience in training government officials to improve their writing. He operates from this springboard: ""Effective writing is clear thinking, well expressed."" His own writing, with its Flesch tone, is very much to the point, as he tackles the problems of preparing to write, writing, and revision. He deals concisely and inclusively with all elements of style from the planning and organization of a letter, memo, report to the punctuation, the use of human vs. impersonal, etc. Appendices include a list of the most frequently misspelled words (and elsewhere there's a list of words people like and dislike). Essentially for the man who needs to write in connection with his work (rather than for the writer), this is suitably succinct.
