This series contains the invitation to events held at other institutions. The "representation files" are organized alphabetically by the name of the inviting institution and then mostly by academic year. Each event packet is labeled by the institution, event date, event title, and representative sent (if any). Events include presidential inaugurations, anniversary celebrations, commencements, conferences, convocations, dedications, etc. Packets can include the original invitation, correspondence with the hosting institution and the local delegate(s), and responses mailed with the official Columbia University credentials. The files capture the ritual and practice of sending delegates and credentials to fellow institutions.
