Following the narrow definition of the mobile Internet, ‘mobile libraries’ refers to digital libraries accessed by users through mobile phones and wireless networks. In order to explore users’ adoption of mobile libraries, a research model is developed focusing on two psychological factors (flow experience and innovativeness) and two factors oriented to the mobile context (ubiquitous connection and use context). Data collected from digital library users who are also users of the mobile Internet were used to test the model. The findings show that use context not only has a direct impact on users’ intention to adopt mobile libraries, but also partially mediates the effect of flow experience and ubiquitous connection on usage intention. Meanwhile, innovativeness both significantly affects usage intention and negatively moderates the effect of use context on usage intention. Findings and implications for theory and practice are discussed.
