Abstract
It is a short review resp. an annotation of a book entitled Czechoslovakism, which was published at the end of 2019 as a result of several years of cooperation between Czech and Slovak historians. The article deals with the individual chapters of the publication and in each of them it tries to point out a new approach or knowledge that its author brings to the research on this topic.
The annotation highlights the overall new contribution of the publication, which it brings to research and discussion about the phenomenon of Czechoslovakism, and which the author of the annotation herself deals with in her research.
