Series II has been divided into three subseries: 1. Academics and Academic Business (1929-1983), 2. Professional Organizations and Activities (1934-1986), and 3. Publishing Activities (1937-1987).
The first subseries (Academics and Academic Business) mainly concerns de Finetti's activities in the academic environment such as teaching, university politics and reform, research funding, and job applications. It also includes material on his appeal against the denied appointment to the chair of financial mathematics at the University of Trieste in 1942.
Material in the second subseries (Professional Organizations and Activities) relates largely to de Finetti's membership in professional and scientific organizations, such as the Accademia dei Lincei, his collaboration with professional journals, and his participation at various conferences.
The third subseries (Publishing Activities) features correspondence with publishers, friends, and colleagues, page proofs, drafts, reviews, offprints, and related legal material.
