In 2021, Anton Vetterle (Schwäbischer Münzclub Augsburg) published a new standard work for the coins of the city of Augsburg:
Anton Vetterle: "The coins of the free imperial city of Augsburg from 1521 to 1805" (https://www.worldcat.org/title/mnzen-der-freie-reichsstadt-augsburg-von-1521-bis-1805-katalog/oclc/ 1252701421&referer=brief_results).
This work updates and expands the two Forster catalogs and is definitely worth including on Numista as a reference work.
