A front-page byline in The New York Times! A People magazine cover story! A travel assignment in Katmandu! Dream on. "This is a book," says author Lucy V. Parker, "about commercial writing, business writing, nonfiction writing. It is a book about obtaining practical, often unglamorous assignments that can pay the bills." Sure, celebrity profiles and investigative journalism can be thrilling, but so can paying the rent. Besides, someone has to write all those newsletters, brochures, press releases, speeches, instructional manuals, and articles for employee magazines. With Parker's help, you can write a business plan, form a business, market your services, learn what to charge (and how to collect your due), and deal with taxes and contracts. Parker even tells you how to cope with the loneliness inherent in running a solo venture. Hint: online chat rooms are OK, but "people breaks" are better. With profiles of 10 successful professionals from a variety of specialties and a list of 60 key assignments for home-based writers. --Jane Steinberg
