Traditionally, appraisal decisions for a congressional collection have been made after the arrival of the collection at a repository. In this case, the collection was the papers of Senator John J. Williams of Delaware. Williams represented Delaware in the United States Senate from 1947 until 1970, and was known as "the Conscience of the Senate" for his honest pursuit of integrity in government while serving on both the finance and foreign relations committees. Processing the Williams papers was a dedicated two-year project. A project archivist was hired in 1988 and , shortly afterwards, a technician assistant. The project archivist made all of the appraisal decisions, and the technician followed guidelines to assist with sampling selected files . Processing was done in a year and a half; a finding aid , summary guide, and an exhibition were completed by the end of the project in September 1990.
