This article concerns the origins of the Lutheran Church Library, the current G.R. Tschammer Library and Archive of the Evangelical Church of the Augsburg Confession Parish of Cieszyn. The beginnings of the largest Lutheran antique book repository in Poland, among the most interesting in Silesia, are tied directly with the 1709 consent for building an Evangelical church in the Cieszyn area after the time of Counter-Reformation. The author here presents the most recent developments in research into the beginnings of the Tschammer Library, which were made possible due to access to the parish archive, which allowed for detailed and extensive analysis. Hitherto all publications on the subject paid little attention to the origin of the book repository, due to lack of access to the archives, as well as the lack of detailed analysis of the provenance records in the antique books. The two sources allowed for the date of creation and development of the Church Library to be shifted by nearly forty years, as well as allowing a closer look at their first donors in the years 1710-1730.
