This paper describes the characteristics of the mission, vision and strategy and their impact on other business factors. The components are developed in accordance with their marketing significance and their general position in the library business. An insight is given into the standards to which the library refers in its work and the business aspect of the library is explained in more detail. The features were applied in the analysis of a sample of Croatian and foreign libraries where strategic documents were processed and key items derived from them. The theoretical work mentions library collections, their content and maintenance. The characteristics of staff, as an important and influential factor in business, are described through guidelines and a code of ethics that dictate the rules by which employees should be guided in business. The analysis gives concrete examples of library operations and highlights individual items that make each of the libraries unique. An information institution development strategy is often linked to a city-specific culture strategy. The activities of the library are aimed at encouraging literacy and reading, preservation of cultural heritage through the organization of workshops and lectures. Also, as information technology advances, the presence of the library is important in this type of business as well. Employees encourage information literacy and build e-services and digital collections. Insight into the business of libraries provides a broader picture of the library as a business facility and system that serves the community for the purpose of disseminating information and knowledge.
