Senator Tom Harkin, an Iowa Democrat, has announced that he will not donate his papers to an institute named for him at Iowa State, The Des Moines Register reported. That institute may now change its name and focus, and money donated to it may be returned. The dispute centers on what Harkin and some see as limits on academic freedom. Agriculture research supported by the institute must be done in collaboration with other institutes at Iowa State. While university officials say that requirement is innocuous, others see it limiting academic freedom by preventing solo work by those affiliated with the institute.
