The purpose of this study is to investigate if there is a relationship between reading to schoolchildren picture books on a library and its effects on their library use. 14 library-related picture books and 64 students in third grade of an elementary school in Suwon were selected for reading activities for 7 weeks to students with once a week program. The survey was conducted to those students to observe the changes in students' recognition on a library and a librarian before and after reading activities. As a result, it appears to be some improvements on reading attitude, understanding and awareness of function and using ways of school libraries, and the role of a school librarian. However, no changes have been made on the recognition of reading activities and a librarian. Based on these results, the study suggest that reading picture books to children could be continuous and highly effective methods to library education system.
