The purpose of this study is to recommend that all types of libraries in Korea develop a disaster plan. The materials in the library are apt to get damaged at once by such disasters as fire or flood. It is fortunate that we have not found any big disasters in Korean libraries, considering the many cases of major disasters which have destroyed materials in the libraries of foreign countries.
  In spite of the possibility of disaster at any moment, that will cause the library's loss of function, there are no libraries that have a disaster plan in Korea. A disaster plan is a guidance by which materials are conserved at ordinary times, protected and recovered in contingency. It consists of four elements: prevention, preparedness, reaction and recovery. As libraries function by bibliographic data and user data in automation system, it is also recommended to prepare system protection in the disaster plan.
