The presented study is an introduction to the passage of the Nitra seat based on the existing manuscripts of Matej Bel, but also his assistants (former students and collaborators) who participated in the design of the final form of the written volume. A key element of the paper is the basic characteristics of the source documents, which directly related to the Nitra capital, as well as the list of contributors.
