This study focuses on Turkish scholars' information use. Using citation analysis, it investigates a total of 197,687 publications in our main scientific disciplines (pure sciences, engineering, social sciences and arts & humanities) extracted from Web of Science (1928-2009). Authors (at least one of them) of these publications were all affiliated with Turkish institutions. Differences between these disciplines and between their sub-disciplines in terms of average author number, multiple authorship, half-life, publication types, journals characteristics were determined. Findings of this study can be helpful for national-level policy making on scientific productivity that will help Turkish scholarship to reach international level.
