NEW YORK - Alice Walker, who turns 70 later this month, is thinking about her legacy.
Over the past few years, the Pulitzer Prize-winning author has donated her papers to Emory University, permitted "The Color Purple" to be released as an e-book and reached a deal with Simon & Schuster to publish excerpts from journals she has kept for decades.
Walker has also participated in the documentary "Alice Walker: Beauty in Truth," scheduled to air Friday night on PBS stations as part of the "American Masters" series.
"I don't have this feeling that 70 is really old," says Walker, who notes one ancestor lived to 125. "But I do feel it's helpful if you're thinking about the coming generations to leave your work in a form that people can relate to."
