A large database of more than 400 existing historical atlases released after 1950 was created as a result of an extensive analytic research within the preparation of cartographic works on the Czech Historical Atlas. The database was published in the form of a web application that allows the user to reveal and analyse associated information about historical atlases across interactive dashboards. To improve the information value of the database, the authors decided to arrange further possibilities of data excerption with the use of specialized data visualization methods that may reveal additional information and new phenomena which are not clearly visible from the database itself. The performed analyses supplement the paper in the form of diagrams and charts and present the data from various perspectives with the focus on similarities and differences between the cartographic and the thematic content of the historical atlases in the publishing countries, the changes in the thematic focus of the atlases or changes in the use of methods of thematic cartography in atlas works over time. The authors also deal with relations between the thematic focus of the atlas and the applied methods of thematic cartography. All analyses are performed on the sample of 88 atlas works.Historical atlases and their characteristics were selected according to the methodology concept devised by Bláha and Močičková [3]. On the basis of two criteria defining the time and geographical delimitation of historical atlases for the study, two students of the Czech Technical University in Prague collected information about selected Czech (Czechoslovak) and foreign historical atlases released after 1950. During the first phase, the students searched for the standard bibliographic description (title, author, publisher, country of origin, language, etc.) of more than 400 atlases in electronic catalogues of Czech and foreign libraries. In addition, each item was provided with information on the focus category of the atlas (e.g. politics, demography, military issues) and with a list of libraries in which the atlas is physically stored. Due to the geographical delimitation of the studied atlas works, the database consists mainly of the atlases of Czech (106) and German production (97), followed by the atlases from France (65) and the United Kingdom (47), which account for more than three quarters of the database.
