The aim of this article is to show the course of castle-library auctions in the 1930s on the specific example of the Dietrichstein family. The sale of the Mikulov castle library is placed in the broader context of legal and social changes after the collapse of the Habsburg monarchy and the establishment of the First Czechoslovak Republic (the abolition of fideicommissum, a change in the status of the former nobility). and Kristýna Kaucká.
The catastrophic floods in the Czech lands in July 1997 and August 2002 showed that historical flood memory had been lost. The little used sources to recover it include early printed books. This article brings a selection of several exceptional flood cases captured by printed documents from the 16th-18th centuries. Extant early printed books and the information that they contain (verified from other sources where possible) suitably complement and extend the potential of historical hydrology and meteorology for the study and documentation of early floods that occurred before the beginning of instrumental observations and measurements. and Jan Munzar, Stanislav Ondráček, Lubor Kysučan.
