The Doris Duke Charitable Foundation is giving the Kennedy Center $3 million to continue presenting international festivals and the Library of Congress $1 million to purchase the archives of dance innovator Martha Graham.

The grants, which will be announced by the New York-based foundation today, are part of a $5.5 million package to four performing arts centers.

The money for the Kennedy Center is earmarked to help develop its international festivals. The center plans to continue its African Odyssey series, is preparing a lineup of Irish programs for next year and is considering a Latin American festival.

"The nice thing about the Duke money is that we don't have too many funds that are designated for international programs," said Kevin McMahon, the center's executive vice president. The grant's first $2 million must be matched dollar for dollar through center fund-raising over the next three years. The remaining $1 million will go directly to the production of festivals.

The Library of Congress had been looking for help in acquiring the Graham archives from her estate. The materials, which cover the 65-year career of one of the century's most influential artists, range from choreographic notes to films.

"We had an agreement to purchase the materials, but we didn't have the money in hand to do that," said Vicky Risner, the library's dance specialist.

The Duke grant will enable the library, in conjunction with the estate, to ask the still-performing Martha Graham Dance Company to reconstruct as many as five of Graham's most famous works. The library plans to present them, beginning in November, at the Coolidge Auditorium and videotape them for archival and educational purposes.

"We didn't want the materials to be dead but to keep her legacy alive through the creation of additional materials that document the choreography and her work," Risner said.

The foundation was created from the fortune philanthropist Doris Duke left when she died in 1993. It mainly supports environmental, arts and medical research groups.

The other grants it awarded yesterday were $1.4 million to Appalshop, a cultural center in Kentucky's Appalachian Mountains, and $100,000 to Dance Umbrella, a producer of contemporary dance in Boston.
