Yes! On the library's homepage, look for the Live Chat icon at the bottom right corner of the first screen. During the regular semester, LiveChat with a librarian is always available (24 hours/day and 7 days/week). AU librarians answer chat on weekdays. Off-site librarians answer chat over night and on weekends. Hours are shortened during academic breaks and are closed when the university is closed.
