At the International Congress held in Athens in 1912, it was proposed that the next Congress be held in Oxford in 1915. This was then postponed to September 1916. However the hostilities of World War One led to the discussion of the appropriateness of holding an International Congress. The material within this series consists of correspondence concerning that discussion. They are:
- "Extract from a letter from Professor Sylvain Lévi to Sir George Grierson, dated February 19th 1915" in which he writes of the difficulties of organising an international congress at that time and offers some alternatives.
- "Extract from a letter from Professor Sylvain Lévi to Sir George Grierson, dated 2 February 1916" and a note concerning Grierson's reply. The letter expresses Lévi's concerns and the possibility of a Congress with only allied nations involved.
- "Extract from a letter from Professor Sylvain Lévi to Sir George Grierson, dated April 1, 1916" in which he writes concerning the possibility for involvement of some organisations including the Royal Asiatic Society, the Pali Text Society, the Institut de France, the British Academy and the Royal Society.
- Letter from [Sir George Grierson] to potential attendees of a meeting fixed by Lord Reay of those being consulted about Sylvain Lévi's letters. Dated 10 May 1916. With this letter are copies of correspondence to Grierson from Professor T.W. Rhys Davids of Pali Text Society, Dr. J.F. Fleet, Dr F.W. Thomas, and F.E. Pargiter expressing their opinions, dated 22 March - 10 May 1916.
