One of the primary challenges of conducting information encountering (IE) research is the difficulty in capturing people's IE experiences. The purpose of this paper is to develop a general description framework of IE experiences as guidance for participants to record diary entries in diary studies of IE.

340 descriptions of IE incidents were collected from 18 previous IE studies as secondary data. A thematic analysis of the secondary data engendered a general description framework of IE experiences composed of 9 main themes and 31 sub-themes. The framework was then applied in a diary study to investigate Generation Z's online IE behavior.

The nine main themes of the framework, including “environment”, “foreground activity”, “stimulus noticed”, “reaction to stimulus”, “content examined”, “interaction with encountered information”, “value of experience”, “pre-encountering emotional state”, and “post-encountering emotional state”, were used to create a diary questionnaire for collecting IE incidents. The sub-themes were refined and organized into a coding scheme for the content analysis of the incidents collected. The diary study collected 255 valid IE incidents which were analyzed based on three phases, that is, pre-encountering, encountering, and post-encountering.

The value of this study consists in its methodological contributions. First, it makes creative use of secondary data accumulated in the literature and derives from the thematic analysis a general framework which people follow to describe their IE experiences. Second, it demonstrates the great potential of diaries for data collection in IE research through the successful application of the general description framework of IE experiences in a diary study. Third, the diary questionnaire created based on the framework provides sufficient guidance in eliciting complete and detailed IE incidents.

This paper aims to review the literature on mobile information services. It considers only peer-reviewed papers published in English between 2004 and 2014.

The method of systematic review was adopted to collect and analyse the relevant literature. The searches were conducted during the last week of July 2014 on different databases, and in total, 76 papers were considered after applying inclusion and exclusion criteria.

Seven themes emerged: “introducing mobile libraries”, “reporting on current trends”, “exploring users’ perceptions of libraries’ mobile services”, “presenting libraries’ mobile services”, “presenting mobile technology use in libraries”, “reporting case studies” and “reporting on evaluation of libraries’ mobile services”. It is evident that research on mobile libraries is very recent and focuses mainly on raising the Library and Information Science profession’s awareness of providing mobile information services.

This literature review focused only on peer-reviewed papers published between 2004 and 2014 in English.

This paper summarises and critically presents the relevant literature on libraries offering mobile information services. It informs libraries and librarians’ understanding of recent developments in mobile technology for the successful provision of information services.

This study aims to explore whether the usability of user experience for mobile library application plays a mediating role in the relation between the success factors of information systems and net benefit.

The theoretical model of “information system success factor–user experience usability–net benefit” was constructed. A questionnaire was conducted at the Nankai University. The mediating effects of the usability of the mobile library application on information system success factors and net benefit were examined using hierarchical linear regression and structural equations.

First, the usability of user experiences is positively correlated to information quality, system quality and service quality. Second, user experience usability has a significant mediating effect on the relation between information system success factors and net benefit.

This study improves upon the DeLone and McLean model, connects the usability of user experience with the model and constructs the success factor mechanism of the mobile library application. It provides a theoretical basis for interpreting the relation between the mobile library application and users.
