The paper presents a project for the development of a national rulebook for cataloging entitled "Rules for the description and access to materials in libraries, archives and museums" (Rules KAM) which will be applied in this thesis to the description of film material. The aim of this thesis is to showcase the possibilities of applying the KAM Rulebook to the description of film material. The purpose of this paper is to investigate whether the new national rulebook for cataloging is applicable to the description of film material. Moreover, it is to see whether this description is possible with the help of the Rules in relation to the application of common elements of film material description according to ISBD, which are possible shortcomings , as well as whether the Rules prescribe elements of description that have not been common and applicable so far, but contribute to a better description. The first part of the paper will present the Rules for the description and access of materials in libraries, archives and museums, including the description of the project "Development, publication and maintenance of national regulations for cataloging", as well as the structure and content of the Rules. Furthermore, in the second part of the paper, a description of the film material and its basic features follows will be provided. In the research part of the paper, the film material will be described first with the help of ISBD and then with the help of the "Rules for the description and access to material in libraries, archives and museums" and to explore the possibilities of applying these Rules to the description of film material. It will be investigated whether the "Rules for the description and access to materials in libraries, archives and museums" are appropriate for the description of the film, whether the Rules contain all the necessary elements of description, and whether the Rules prescribe some additional elements that can be used to describe the film material, and will furthermore, contribute to either easier finding of film material in the catalogue or better understanding of the catalogue record itself.
