This paper presents an extensive reading project conducted on an e-book system.We use picture books and comic books as reading materials, and provide an online forum where students can share and discuss their impressions of these. As initial results of the project, we show students’ reading patterns, the influence of the online forum on reading amounts, and the influence of reading amounts on performance. The results indicate that the forum may stimulate students and encourage them to continue doing extensive reading.We also observed moderate correlations between the reading amounts and exam scores
