Intended for the adult who needs writing skills for career purposes, this three-part book presents principles rather than mechanical rules for achieving effective communication through writing. The first section of the book offers specific guidelines on communicative attitude, content, perspective, theme, organization, and revision. The middle portion discusses common writing errors involving grammar, redundancy, sentence structure, and language choice. The final section presents a guide for handling such practical writing problems as publishing, editing, proposal writing, writing references, citations, and footnotes, statistics, press releases, resumes, and indexing. Appendixes cover the following topics: proofreading, inductive and deductive writing, basic techniques for making charts and graphs, and exercises in writing. (MAI)
