"Privacy," according to Justice of the United States Supreme Court William 0. Douglas, "involves the choice of the individual to disclose or to reveal what he believes, what he thinks, what he possesses. The individual," he believed, "should have the freedom to select for himself the time and circumstances when he will share his secrets with others and decide the extent of that sharing." For the private manuscript repository the protection of an individual's right to privacy, at least that of the donor, presents no insurmountable problems. Donors may simply purge files in advance of deposit or place certain restrictions on their disclosure.
