This study assesses research patterns and trends of library and information science(LIS) in Korea by applying bibliometric analysis. For the study, 2,400 peer-reviewed publications from 2001 to 2010(including conference proceedings) published by 159 LIS professors in Korea were analyzed by year, author, affiliation and journal. The study findings showed an increasing trend in collaboration(52.75% of total publications with single authors and 47.25% with multiple authors) among LIS professors in Korea, robust publication patterns of Korean LIS faculty(average 1.51 publications per year), and an increasing number in foreign publications(170 publications). The study results also suggested an internationalization of LIS in Korea. Specifically, the study found a higher rate of Korean LIS faculty with foreign degrees than in previous years as well as a higher publication rate of professors with international degrees. The analysis of publication patterns conducted by the study, which is a first step in our aim to establish a multi-faceted approach for assessing the impact of scholarly work, will be followed up with analysis of references and citations to evaluate the quality of publications.
