This study aims at analyzing research trends of library management and suggesting future tasks of this area in Korea. This is a study following the previous study which was done in 2014. For this purpose, this study analyzed 323 papers of library management area among the library and information science papers which have been published from 2014 to 2020 at the four academic journals of the National Research Foundation of Korea.

The amount of papers in library management has increased, compared to 36 papers annually published which were checked at the previous study. The analysis on the research trends of sub-fields of library management showed that high research performance has been done at the sub-fields like ‘general management’, ‘human resource management’, ‘measurement and evaluation’. However, there has still been less performance in the sub-fields like ‘marketing’, ‘organization management’, ‘budget management’, which was also shown at the previous study.
