Most studies on Chinese academic resource selection have used a qualitative approach, focusing on issues such as resource distribution and accessibility. To fill the research gap, the current article analyses the responses of 190 undergraduate students of the Peking University to a questionnaire survey, revealing various academic resources' access methods, usage frequency, and access obstacles, while exploring underlying factors affecting resource usage with a focus on the language impacts.

Electronic resources were displacing printed resources. Based on Bass's innovation diffusion model, diffusion of different electronic resources among undergraduate students fit well with the S-curve, though with significantly different slopes, for ...
