[Purpose/significance] Discovering the interdisciplinary literature is an important prerequisite for interdisciplinary research. Finding domain-related interdisciplinary publications from vast amounts of literature quickly and accurately will help researchers understand the new tendency of interdisciplinarity and identify the focal and hot themes of the field rapidly. This paper presents a novel approach to discover the interdisciplinary literature based on Rao-Stirling diversity indices. Focusing on the case study in the field of nanoscience & nanotechnology, we discussed the feasibility of the method.[Method/process] Based on the nanoscience and nanotechnology publications in the Web of Science, we mapped references to the Web of Science Category, constructed the subject distribution matrix and calculated the interdisciplinary measure indices of the documents based on Python and R to find the interdisciplinary literature.[Result/conclusion] The paper shows that the interdisciplinary literature discovery method based on Rao-Stirling diversity indices can measure the degree of interdisciplinarity in the publication level and discover the interdisciplinary publications in the field of nanoscience and nanotechnology. The method could be applied to other research fields.
