A public library is an establishment that develops its tasks and activities for the benefit of society. Today it is increasingly focused on education, informing and the social inclusion and cultural progress. To accomplish all of that it is important that it secures a wide spectrum of ideas for its users, through different sources that correspond to the different needs of the users. Library also need to encourage cultural diversity and inter-cultural dialogue. The promotion of cultural diversity is especially interesting in the context of the film in public libraries. The film is a powerful medium that creates an image of the society and helps in the development of cultural understanding. In scientific literature it’s hard to find research dealing with film collections in Croatian public libraries, especially when dealing with animated films. For example, there is no research dealing with the origins of animated films being borrowed or the diverse cultural themes in those films. Because of all that, the aim of this paper is to get a more complete insight in the variety of animated films which are borrowed in Croatian public libraries. Also aim of this paper is to get an insight in promotional activities of libraries with regard to their film collections. The goal of this paper is to explore which animated films are being borrowed by users in Croatian public libraries to determine the variety of the films in regard to the country and the time of production. Additionally,the aim is to explore how much and in what ways do public libraries promote their collection of animated films in their web sites. The analysis of four Croatian public libraries’ catalogues enabled the comparison according to the diversity of the films being borrowed most often and the popularity of the borrowing of films. The research certainly emphasizes the importance of diversity in libraries’ collections, especially the collections of animated films in public libraries. In addition, the paper displays the current state and possibilities for the development of diverse animated collections in Croatian public libraries.
