(I)-In Vol. 34. pp. 178-184.<br> It was not until the late sixties or early seventies that undergraduate students could borrow books from their university central libraries without any permission from their professors. This article traced the changes in the borrowing regulations for undergraduate students from the Meiji era (1868-1912) through the Taisho era (1913-1926).<br> In the Meiji era, students could hardly get textbooks written in foreign languages, so they were allowed to check out such textbooks from libraries with their professors' permission. Concerning other books besides textbooks, for instance at the Imperial University, which was the oldest university in Japan, undergraduate students could take them out only during summer vacation with their professors' permission.<br> There were no private universities in the Meiji era. Private colleges had such small collections and so few students when they were established that there were no strict rules in their libraries. According to 'Daigakurei', some private colleges were approved as universities by the government in 1920. In Rissho University and St. Paul's University (Rikkyo) libraries we found records showing that undergraduate students checked out books during the academic term.<br> Generally speaking, in the early days, library regulations were fairly simple and undergracluate students could borrow books easily, but as enrollments increased, library regulations became stricter.<br> <br> (II)-In this volume<br> When the Great Kanto earrthquake occurred in 1923, the Tokyo Imperial University and other private university libraries located in the Kanda area were damaged. The Tokyo Imperial University built a new library in 1928. Open stacks were put in the free access reading room. It was very convenient for students, because in the old library they had to get a professor's permission in order to get into the stack room. New regulations were made, but there were no rules to allow undergraduate students to check out books. This situation continued for 34 years. Among national university libraries, the Nagoya University library was the first to allow Undergraduate students to check out books without a professor's permission.<br> Private university libraries adopted this rule from the beginning of the sixties and gradllally it became more popular.<br> After the widespread university disturbances from the 1960s to the beginning of the 1970s, libraries also realized that they needed to serve not only faculties but also undergraduate students. The number of books which could be checked out was increased and as well as the number of books in open stacks.<br> In conclusion, university libraries Should have two functions. One is for research and the other is for education. In other words they have to serve faculty members and undergraduate students equally. Through tracing the history of university libraries, the author found that in order to change regulations or adopt new plans, librarians must cooperate with faculty members and administration.
