One of the big questions we are often asked about at Ask a Librarian is – when are people using the service…  Is it similar to in-person usage?  Is there a run at 11pm?

The following graphs look at total usage in September by time of day by day of week.  The first chart is all chats (local desks, academic queue and the collaborative queue).  The second graph is the main collaborative queue and the third chart is the academic queue (note- this queue is only open 10am-pm M-F ET).
