An online questionnaire survey was conducted from October to December 2011 in cooperation with 45 institutions in Japan. As a result, 3,922 valid responses from researchers (faculty and doctoral students) across various fields were collected. Through the analyses from multiple viewpoints, the survey results showed a significant progress in researchers' use of online resources and obvious changes in their attitude (preference) and reading-behavior. The difference in e-journals usage by research discipline is strongly associated with the degree of dependence on domestic documents written in Japanese. It is clarified again, therefore, that the delay of digitization of domestic documents should be resolved to avoid the separate service models for printed materials and digital documents.
