Some notes on the card file of August Sedláček: The study discusses the card file, which is part of the written estate of the important Czech historian August Sedláček (1843–1926) and is a unique and extraordinarily extensive file of more than 400,000 index cards. The study deals with the question of the ratio of the card file to the printed work of A. Sedláček and reminds of the advantages of its digitization.
