This paper attempts to reveal interdisciplinarity through analysis of the literature belonging to multiple subject bibliographies of the different disciplines in social sciences. The multidisciplinary literature was proved by extracting entries from International Bibliography of the Social Sciences (IBSS), a comprehensive bibliography in social sciences, which comprises four series of cultural anthropology, economics, political science and sociology. From 42,376 monograph records in the IBSS (1981-85), 2,007 items were identified as the multidisciplinary literature by detecting entries to be duplicate among the four series, and 993 items to which each classification number of economics and sociology were doubly assigned were found. The analysis of these items showed close relationships between the four disciplines. especially anthropology and sociology, and allowed us to obtain a cognitive map of interdisciplinary subject areas in social sciences. In particular, the paper suggests that the relationships between subfields in the disciplines are attributed to several common subjects in two or more subfields such as religion, ethnic groups, social stratification, population, labor, international relationship and so on.
