This student library subsection of the BDL lists both the extant and the virtual titles which Beckett is known or thought to have read during the years 1923-1931, first as a student at Trinity College Dublin, then as a lecturer at the École Normale Supérieure in Paris and TCD. The extant student library consists of the books dating from this timeframe that have been preserved in various collections, most importantly in Beckett's apartment in Paris. The virtual student library, by contrast, contains the books which, according to specific sources, Beckett read or may have read as a student and lecturer but which have not been preserved.

Read: by October 1927, Summer 1929, Summer 1930.
Beckett first read part of volume I in a virtual edition for the final examination at TCD in October 1927 (Moderatorship). Although signed in student fashion "S. B. Beckett", the volume that opens the Nouvelle révue française collection was probably only acquired early in 1928 together with the other fifteen volumes. A letter to Thomas MacGreevy dated summer 1929 reveals Beckett having finished reading the first volume, Du côté de chez Swann, finding it "strangely uneven" (LSB I, 11). Beckett wrote to MacGreevy on 7 August 1930 that he had started re-reading À la recherche du temps perdu (Pilling 2006, 26).
