The purpose of this study is to select keywords that can recommend books by personality type, and to test whether the chosen keywords can be actually used in the categorization and customized recommendation of books for each personality type. To achieve the research goal, this study chose books that match the level of fifth and sixth grade elementary school students and first grade middle school students and commissioned an expert group to categorize the books into groups that are preferred by each personality type. As a result of the classification, half of the books in which more than five experts agreed showed high consensus. In addition, the results of classifying books by personality type with keywords extracted by the automatic word extraction system by collecting the book review data of the selected books were similar to the results of the final judgement by the expert group, except for a few books. In conclusion, this study proved that it is possible to classify and recommend books that are likely to be preferred by different personality types using review keywords.

The purpose of this study is to examine the possibility of using the WorldCat, an International Union Catalog operated by OCLC as a tool for analyzing the trend of knowledge distribution in libraries around the world. In this study, four subject keywords, that is, Korea, Korean, Japan, and Japanese, were used to search materials related to Korea and Japan, and four facets, including medium, genre, language, and user level, were used to categorize search results from the WorldCat. The result shows that information resources related to Korea held by libraries around the world are only a little more than a third of Japan-related information resources. Especially Korea-related information resources for juveniles are less in numbers and lack in diversity in languages, media and genres, when compared with Japan-related information resources. Also an examination of two bibliographic records demonstrates that viewpoints expressed in user contributed reviews might affect diffusion of knowledge on certain subjects in the Next Generation Library Catalog.
