The aim of this study is to define purposes and functions of integrated access to bibliographic data in museums, archives, and libraries that have been characterized as institutions of cultural memory and to propose a theoretical framework. These institutions' joint functionality are discussed around interoperability models and the relationship between data content standards and AACR2 is established. The study shows that the traditional approach characterized as "classification by document types" has given its place to using shared common rules and information access. As for implementation, this study addresses the question of the preparation of the Istanbul University Central Library and the Istanbul University cultural and biological collections and their sustainability, providing samples of bibliographic records for 3-D collection materials using MARC format codes. In conclusion, the study demonstrates that the information and documentation centers are only recently being established with a "shared functionality" approach in information and document management on electronic environment in Turkey. Descriptive and comparative methods and interviews, observations, and questionnaires were used as instruments for data collection
