During closing days, the Library’s information systems are still available for users to do searches and to use the open access electronic resources.

Besides daily care of software/ hardware performances of information systems, library’s mechanical and electricity system, environmental cleaning, shelving condition, etc., the Library needs to do thorough routine check up and necessary maintenance at one-week interval so that library could retain its good condition to best serve our users. In consideration of most convenient time for people to use libraries, the NCL opens on weekends, therefore, makes Mondays as closed day for such routine check up and maintenance. However, even the Library is physically closed on Mondays, the information systems are still available for users to do searches.

There are specific rooms for special thematic collections located at 4th floor and above. There are very few people use such area after 17:00. For cost effective reason, such area and rooms are closed after 17:00 on all opening days. Besides, the Rare Books Room is closed on Sunday.

However, to allow researchers best use the research carrel, the opening hours of research carrel area is the same with 2^nd and 3^rd floor reading area.
