The content of a Stadtbuch varies with growing literacy. The oldest records contain a mixed variety (Stadtbuch mit vermischtem Inhalt), such as laying down the law for the city, collecting judgments. Legal certainty was created and citizens received parameters by which to interact with the city administration, legal issues, business affairs etc. For instance, land records were created by town clerks and stored by authority of the city council. Such records then received public credibility and became evidential. Since the 14th century city records became more categorized. The matters of the city council were kept separate from business between citizens, such as property issues and marriage contracts. There was a book for financial matters, statutes, city law and ordinances as well as for judicial protocols, in and outgoing correspondence, citizenship records and expatriations. A Stadtbuch allows a glimpse into the life of citizenry and touches on the development of city law, politics, social structure and population statistics. Source: Wikipedia

In Germany as well as in the Kingdom of Saxony, authorities kept the so called Bürgerbücher or Bürgerrollen (lists of people who lived in cities, who had been given the right to live in a city (Neubürger) because they paid a sum of money for the privilege ( the sum was lower when a new citizen married a girl or a widow from a particular city). They now had the privilege to practise a profession, they had voting rights, but they also had to pay taxes and defend the city. Well into the 19th century such books are a well-documented source in which one can find where the new citizens originated from. Bürgerbücher are the invention of cities, therefore, one can find such documents only in cities. When cities did not publish Bürgerbücher one may find information about new citizens in their yearly accounting books (Stadtrechnungen or Ratsprotokolle).
