Beatrice Webb, the famous sociologist and political activist, reported in 1926: "'Every one agrees nowadays', observe the most noted French writers on the study of history, 'that it is advisable to collect materials on separate cards or slips of paper. . . . The advantages of this artifice are obvious; the detachability of the slips enables us to group them at will in a host of different combinations; if necessary, to change their places; it is easy to bring texts of the same kind together, and to incorporate additions, as they are acquired, in the interior of the groups to which they belong.'" 
Webb 1926, p. 363. The number of scholars who have used the index card method is legion, especially in sociology and anthropology, but also in many other subjects. Claude Lévy-Strauss learned their use from Marcel Mauss and others, Roland Barthes used them, Charles Sanders Peirce relied on them, and William Van Orman Quine wrote his lectures on them, etc.
