Appendixes I, II, III, and IV feature many items that can make your letter writing a more pleasant and less arduous task. All four appendixes are arranged alphabetically for easy reference.
Appendix I is by no means an all-inclusive list of every word ever used incorrectly. It does, however, include some words that are either tricky to use or often are used incorrectly. If you have a question about how a word or phrase should be used, check Appendix I. If it is not included in the Appendix, you will find a good reference to consult listed in the Bibliography.
Appendix II lists several rules of punctuation that cause confusion or problems in correspondence. For a more extensive discussion of the proper use of punctuation, there are several good references available. I recommend: The Chicago Manual of Style, Fourteenth Edition (Chicago: The University of Chicago Press, 1993).
Appendix III is divided into two categories. The first gives a list of two-letter state abbreviations. The second lists common abbreviations. Abbreviations should be used sparingly in your correspondence. Occasionally you will receive a letter or memorandum that contains an abbreviation.
