Friedrich Ast

The sale catalogue, drawn up at Ast’s death, lists 1,313 bibliographic descriptions numbered continuously, with no subdivisions for subject or author. An index on the last page eases consultation, grouping the books in some categories (e.g., "Oekonomie und Technologie: nr. 1022, 1172, 1195"). This indicates that the single number corresponds to a work with that topic or, more commonly, that from that number on there are texts dealing with that topic.
