The purpose of this research study is to measure and assess the potentials and effects of online audio-book resources in fostering young children's motivation to read. The research study involved two groups of 5`h- and 6`h-grade elementary-school students in Hong Kong - measuring their reading motivation, and learning from an online audio-book resource, Naxos Spoken Word Library (NSWL) in the context of a school-library setting in Hong Kong. A total number of 292 participants (students from two different international elementary schools (Bradbury and Kingston International Elementary School) in Hong Kong were invited to take part in this study. Students' library usage, reading habits, and their attitudes and ratings on the chosen audio-book resource were recorded, measured and evaluated through the use of a set of self-completed questionnaires. The data sources included questionnaire surveys on students, classroom teachers, school-library staff, and parents, as well as focus group interviews on NS WL student users. The duration of this research study was five months, whilst data collection was conducted between October 2006 and March 2007. The major findings were that out of all 260 respondents, 52% indicated they had used NSWL. Amongst these 136 NSWL users: 33.3% said "Yes", they did enjoy using NSWL; 37.2% said they "Sometimes" enjoyed it; while only 29.5% said they did not enjoy using this online audio resource as they thought its contents not interesting. The chosen online audio resource seemed to have very little influence in enhancing the students' reading motivation in general. In fact, the school librarians witnessed a decrease (10.4 percentage points) in the number of students who visited the school library on a daily basis, and a small decline in the number of students using the school library for "fun". In other words, the availability of audio-books is not necessarily a motivator to read, or to read more amongst the student population under study. Other data collected from the questionnaires and focus groups also indicated girls were more likely than boys to regularly and voluntarily visit and borrow books from the school library, to use the school library for fun, to enjoy reading poetry, and to use NSWL. In order to appeal to a wider audience and enhance motivation to read, the content of audio-books will need to be expanded to include more genres and more diverse content.
