“This is an extremely valuable study of an important body of the work of Samuel Beckett [...] a work of considerable scope and astonishing maturity and assurance [...] will, I am certain, prove of lasting value to future generations of researchers.” —Martin Esslin, external examiner’s report to Åbo Akademi University (1976)

“Clas Zilliacus’s groundbreaking Beckett and Broadcasting (1976), now almost 40 years old – is it possible? – still stands as the definitive study of the radio plays.” —Linda Ben-Zvi, Journal of Beckett Studies (2014)

“[...] virtually all subsequent commentary on the subject stands either explicitly or implicitly in Zilliacus’s shadow.” —John Pilling in Addyman et al. (eds.), Samuel Beckett and BBC Radio (2017)

“[...] his monumental study Beckett and Broadcasting.” —Olga Beloborodova and Pim Verhulst in Samuel Beckett Today/Aujourd’hui (2020)
