[citation needed] As an epigraphist Degrassi was extremely influential, not only in collecting and publishing inscriptions, but also in defining the discipline and training some of those who would become its leading practitioners.
[citation needed] He was elected an International Member of the American Philosophical Society in 1958.
[3] Especially influential was Degrassi's work Inscriptiones latinae liberae rei publicae (abbreviated ILLRP), a collection of Latin inscriptions from the Roman Republic that appeared between 1957 and 1963 in two volumes.
[4] ILLRP "largely replaced" the first volume of the Corpus Inscriptionum Latinarum[5] and was accessible to scholars and students alike.
A review of the work in the journal Classical Philology praised the quality of Degrassi's editing and the importance of the collection.
