N.B. The brief descriptions here are based on the full physical descriptions preceding each Heft in the German edition. All Hefte are understood to be in the Staatsbibliothek zu Berlin—Preussischer Kulturbesitz, except for Hefte 1 and 95, which are in the Beethoven-Haus, Bonn.

Virtually all of the Hefte, except for 1 and 95, bear either annotations or an inserted slip by Anton Schindler or Alexander Wheelock Thayer. Most Hefte also contain librarians’ cataloging numbers, often in ink.

Many of these originally blank booklets have paper shields pasted on to the exterior of the front covers (probably standard at the time of manufacture) for the purchaser to write a title, date, or some other identifier.
