In 2018, the Regional Museum in Teplice provided access to a set of twenty manuscripts of homogeneous content from the 18th century. These are Teplice (shelf marks MS 73–MS 91) and Carlsbad (shelf mark MS 92) spa guest lists. The Teplice lists record spa guests in 1709, 1746, 1769, 1783 and then in a continuous series from 1789 until 1800; the Carlsbad list is related to the year 1797 or 1798.
