Since 1975, HOW and its subsequent editions have been a prominent reference source for business writers, office personnel, and students. With every new edition, HOW has kept pace with changes in our language and the business environment, striving to provide a useful and easy-to-understand reference manual for all professionals involved in organizational operations. It includes detailed and precise information for writing, formatting, and transmitting communications. Unlike other reference books, HOW 13 is tailored for writing style, grammar, mechanics, and techniques in a business/office environment. This text can be used as a stand-alone reference or as a supplement.
