Suddenly, the small-office/home-office market is hot, spawning a number of new how-to books geared toward the soloist. Telecom Made Easy (Aegis Publishing Group, 401-849-4200, 1995, $19.95) is one we like for its thorough coverage of telephones for home and small businesses. Chapters on modems, cellular phones, voice mail, phone systems, and phone bills define terminology and offer checklists for deciding on products and services for different types of users. Especially helpful for do-it-yourselfers, the book includes tips on troubleshooting and repairs, and suggests issues to consider before you buy. Just leafing through this 380-page book will prepare anyone for smarter dealings with salespeople or the phone company.
