Asher, president of a resume service, thinks that job seekers are like small businesses with a product to sell. He offers six steps toward ``working happiness''; for each, he provides tips, techniques, examples, and performance standards. He also offers lists like ``Nine Ways To Get Past Gatekeepers'' and ``Ten Sources for Networking Contacts.'' Rather than trying to compete with other career - change titles like Ronald L. Krannich's Careering and Re-Careering for the 1990s (Impact, 1989), Asher provides a nice complement, advocating an aggressive marketing campaign for developing leads, networking, and closing the deal. A strong bibliography and resource list include the telephone numbers of major libraries' reference desks. Asher ( Overnight Resume , Ten Speed Pr., 1990) does not promise overnight success but offers an overnight beginning. An excellent addition to any career-search collection.-- Joshua Cohen, Mid-Hudson Lib. Sys., Poughkeepsie, N.Y.
