Nanoscience and technology is characterized by nano researchers as an increasingly interdisciplinary domain, drawing upon such disciplines as chemistry, physics, materials science, and computer, electrical, mechanical and biomedical engineering. A key challenge faced by information professionals involved in organizing and providing the related information services is to efficiently identify information resources and to carry out inclusive and effective searches in a diverse and heterogeneous range of digital libraries, web-based databases and search engines. This demand emphasizes the importance of thinking about and developing methodological models for investigating interdisciplinary knowledge organization practices. This 2008 study examined the extent of interdisciplinarity in user queries submitted to the NANOnetBASE digital library. Transaction logs of the digital library were analyzed to explore users' search behaviour patterns and to examine the extent to which user queries were interdisciplinary. The Inspect thesaurus and Classification codes were utilized as the disciplinary or interdisciplinary focus of the queries. The results indicate that 62% of the unique top terms resulting from mapping users' query terms to the INSPEC Classification codes represented two or more disciplines, specifically terms associated with the Classification code 'A' representing "physics." The results contribute to the development of more critical information organization and classification practices in such an increasingly interdisciplinary domain as nanoscience and technology.Subject terms: digital libraries, interdisciplinarity, knowledge organization, information retrieval
Introduction and contextThe interdisciplinary nature of nanoscience and technology poses challenges of efficient searching and retrieval of pertinent information from a wide range of electronic sources. These challenges affect both nano researchers and information professionals who provide library and information services to them. To create better information search services and systems and to properly organize and represent nanotechnology information, it is essential to explore and identify problems and issues associated with interdisciplinary searching in the context of nanotechnology. At present, there is very little research to inform the design and development of information services, knowledge organization systems, user interfaces and digital libraries that can accommodate interdisciplinary searching in nanotechnology. Bates (1996) argues that studying information seeking in interdisciplinary fields can inform us of the needs and problems of people in those fields and notes that interdisciplinary researchers constitute a significant and distinctive class of scholars, deserving of research on their information-seeking behavior.
