This study is to analyze and evaluate copyright protection environment in digital reproduction and transmission, find out problems involved, and suggest recommendations for improvement. Data was collected 50 libraries to which digital reproduction and transmission is permitted under the Copyright Act were surveyed to examine the present states of digitalization and the systems employed. Also, library users, sampled from 5 libraries carrying out all the 6 technical measures obliged by the Copyright Act, were surveyed to examine their use of digital materials and perception on the copyright. After reviewing descriptive statistics, frequency and cross-tabulation analysis were made. The results of the analysis are most of the libraries, except for the industry university libraries, have implemented digital library systems, but the introduction rate of both digital reproduction system and transmission system are high (68.0% and 84.0%, respectively), while that of copyright protection system was low (26.0%). 84.0% of the libraries surveyed digitalize the full text, but the Libraries have digital collection less than 5,000 items, and only 33.3% of them digitalize materials with securing the copyrights. Regulations on copyright protections are not obliged properly, and it appeared that not only users' perception and perception of copyright as well as their use of electronic books are relatively low.
