In preparing a chapter for the IFLA Centenary book that is to be published in 2027, I’ve made heavy use of the published proceedings of the International Library Committee (ILC) for information on the period from 1926 to 1939. I found a lot of fascinating material in the proceedfings, commonly known by the French name, Actes du Comité international des bibliothèques. It struck me that some information about the proceedings should be of interest to other IFLA historians, hence this contribution.
