Part of the current increase in self-employment comes from a trend toward women working out of their homes, says Nancy Rubin, a contributor to a new guidebook for "home-based" business women.

"Thousands of women are discovering that it is possible to remain at home and establish profitable enterprises," she says. "Some are engaged in traditional home industries -- cooking, crafts, child care. Others have businesses as disparate as market research, cat breeding and industrial psychology."

The "how-to" sourcebook, Women Working Home, written and compiled by Marion Behr and Wendy Lazar is available for $12.95 plus $1.25 postage and handling from WWH Press, P.O. Box 237WP, Norwood, N.J. 07648.

The authors of WWH have founded a nationwide network, The National Alliance of Homebased Business Women. Membership is $20 for beginning businesswomen, $25 for those in business at least a year. For information on national and local chapters, write NAHBW, P.O. Box 95, Norwood, N.J. 07648.
