Cartographic material, as it has been proven by scientific research, is largely kept in various scientific and cultural institutions, especially in certain libraries, archives and museum collections. In order to meet the challenges brought by the development of cataloguing standards, cooperation between institutions, and the constant grow of users' demands for better and faster access to information, the next most logical step to be taken is the concept of integration of the cataloguing rules of cartographic material in different institutions and building joint and unified standards. The composing of a new Croatian national cataloguing standard is a chance to achieve this. The paper considers the important issues of integration of cataloguing rules for cartographic material in various institutions, and also attempts to determine the future direction of development.
