Objective: The purpose of this research is to describe and network analysis of bibliographic and manuscripts codicology of basic sciences available in the central library and document center of Tehran University.
 Research Method/approach: In this bibliographic research, network analysis method has been used in order to visualize "subject and language" and "script and paper" networks. Bibliographic and codicology information 1707 for basic sciences manuscripts constitute this research’s statistical population. Checklist is the tool used in this study. Statistical software (Excel, Ucint, NetDraw, PRIMP) and social network analysis were used to analyze the data.
