Belnap and T. B. Steel Jr. published The Logic of Questions and Answers as a timely contribution to erotetics. Beyond propositional logic, they noted that the evolving databases make possible "dossier files on individuals" (page 146) leading to the "problem of privacy in record keeping." The book included a 45-page annotated bibliography of erotetics, sectioned by philosophy, linguistics, automatic question-answering, and pedagogy, compiled by Hubert Schleichert and Urs Egli. On sabbatical, Belnap was visiting professor at the University of California, Irvine and at Indiana University Bloomington, in the falls of 1977, 1978, 1979 with Jon Michael Dunn. In 1982 at Stanford's Center for Advanced Studies in the Behavioral Sciences, and in 1996 at Leipzig, Centrum für Höhere Studien with Heirich Wansing. He was a founding member of the Society for Exact Philosophy, which collaborated with Canadians such as Mario Bunge. Belnap has served as referee for many academic papers. He was elected a Fellow of the American Academy of Arts and Sciences in 2008. Selected works 1975: (with Dorothy L. Grover & Joseph L.
