This extract from the William and Mary Digital Archive describes a digitized record regarding the Bakers Guild:
Bakers' Guild Bylaws and Register (Harburg, Germany), 1668-1809, titled, "Verzeichniß der Articul der Kuchen und Loßbecker Gesellen." (Register of the articles of the cake and pastry[?] baker journeymen) The volume begins with the 47 articles of the cake and pastry baker journeymen, codified in 1668, followed by a wax seal. The articles were revised in 1772 and this "Copia" was bound in the front of the volume. Following the guild regulations are listings of new members to the "Bruederschaft", giving date of entry application, name, place of origin and in most cases the fee paid. Members came from a fairly large geographic area, and in addition to towns near Harburg, places like Leipzig, Berlin and Coburg are mentioned, to name just a few. Interspersed with the guild membership entries are mentionings of the regular meetings or gatherings of the members ("Gesellen"). The meetings were called "Krugtag" and usually took place in an inn. At these gatherings members who were charged with an infraction against guild regulations could be fined and there are some entries showing how much individuals had to pay. Each time a Krugtag is mentioned the amount of money that either came in or was left "in der Lade" (in the drawer?) is listed. Note: Harburg is today a burrough of the city of Hamburg in northern Germany.
