3. Choose the area you would like to study. In this case, we will choose ‘Library – Seoul Campus’.


Please note that you are not allowed to enter the 법학전문도서관 (the second one) – the library is only for the law school students.

4. Select the area where you would like to study. Under ‘열람실명’, these are the different types of study places. If you click on ‘제 # 열람실‘, that means you’re looking for a room where you can do your readings. If you click on ‘제 # 노트북실‘, that means you’re looking for a room where you can use your laptop while studying.

‘사용’ shows the amount of seats are currently occupied and ‘잔여’ tells you the number of available seats left.
