The Zittau library of Christian Weise has an extensive collection of manuscripts, among which we find a number of early modern-era chronicles relating particularly to the six towns of the Lusatian League. One of these is the Zittau Chronicle by Tobias Schnuerer from the 16th century, preserved in a later transcription, in which he chronologically recorded the most important events of his era, including the names of members of the Town Council. Memorial and chronicle records are also included in a collection of manuscripts by Abraham Frenzel (1656-1740). This includes a preserved transcription of an early modern-era chronicle of Sorau (Zary), which details the problems of life in the town and the local authority at the time. Another of Frenzel's preserved manuscripts describes the journey through Europe made by Michael Frank at the end of the sixteenth century, including his visit to Bohemia.
