Series 1 concerns primarily with the University of Virginia School of Law. Teaching notes and clippings, student papers, copies of exams and correspondence related to the subjects he taught. The most substantive of these files are Constitional Law, Commerce, and Real Property.

There is also correspondence and other material on the post-war years of growth at the Law School, as well as on the educational problems of returning veterans. A transition program was a major concern to Ribble, and he communicated with many prominent people in legal education in regard to it.

Near the end of Series I is a substantial collection of material from Ribble's years on the Board of Appeals in Visa Cases. Finally there are some personal letters from his family, as well as what appear to be most of his personal financial papers from the twenties and thirties.

Series III contains correspondence with United States Military Academy and with Ronald R. Richberg related to the Oklahoma Indian Tax Exemption Claims. Also personal correspondence, with few topical folders arranged chronologically.
