The structure of local collections is one of the main tasks of national libraries which demands designed and in advance determined approach and it means responsible and long-term task. This paper includes theorethical basics about local collections: from definition and meaning, types of library structure, purchase, professional processing, protection and digitalization of local structure, to promoting informative-advertising activities. Theorethical basics serve as guidlines on which the state of Local collection of the City library of Županja is investigated, since the main aim of the paper is presentation of the collection itself since the beginning of the collection in 1999 to presentday. Regarding the fact that collection of Županja is pretty small, incomplete in types of structure and insufficiently professionally processed, two successfully formed local collections are exemplified in this paper: collection Essekiana of the Museum Slavonia Osijek and collection Bjelovariana of the National library Petar Preradović in Bjelovar, that are eventually compared to Local collection of Županja. Namely, the aim of conduction of theoretical research and comparative analysis of the two successful collections is to encourage valid deliberation about possibilities of the future ordering of Local collection of the City library of Županja.
