The library of the Centre was built around Frédéric Passy's library of books on international affairs and law, which the Centre purchased from the Passy estate. The librarian was Mlle. Amelot, who had been Passy's secretary. Originally in rooms adjacent to the Centre's offices at 24 rue Pierre Curie, the Passy library moved to the Centre's new headquarters in 1923. Its collections were open to the public.
Includes general correspondence regarding the purchase of books and usage statistics. Some years contain copies of the "Courrier du President Butler," a weekly update of what was in the French news, followed by a list of the clippings sent to Butler.
