Minor publications is name used for a wide range of publications, but the name of the term itself is a debatable and polemical topic that is still not agreed upon today. This paper deals with the research of the use and cataloguing of minor publications within the special library of the Ethnographic Museum in Zagreb and the importance of minor publications for this institution. The paper provides a broad overview of the definitions of minor publications in literature, putting them in relation to the terms ephemera and gray literature. The paper also discusses the issue of defining the term and types of printed matter that fall under the category of minor publications. This paper presents the Ethnographic Museum in Zagreb and its library from its foundation to the present day, and analyzes the cataloguing, classification, storage and purpose of borrowing small print. The library of the Ethnographic Museum in Zagreb uses the ZaKi system for bibliographic processing, and the paper explains the bibliographic organization procedure on one copy, which is supported by photographs. The research was conducted and based on the experience of a student internship in the library of the Ethnographic Museum in Zagreb.
