The paper presents the state and prospects for shared cataloguing and joint representation of library resources in Ukraine. It describes the several projects in Ukraine that combine efforts in cataloguing and creating union catalogues, which are coordina- ted by libraries of different levels. Also, it demonstrates some Ukrainian library projects on authority control. We pay special attention to the Virtual Knowledge project. The main goal of this project is creating a union catalogue as a single access point to all leading universities’ library materials and information resources in order to improve the quality of Ukrainian education and science according to European and international standards. We are also focusing on prospects and ways for the development of shared cataloguing and joint representation of library resources in Ukraine.
