Where Can I Study?

In a city that is bursting with tourists and academicians, you'd think coffee shops would stay open later, past about 5/6.  Last night, for the first time in whole college career, I realized that I take the Student Learning Center for granted.  Jittery Joes, the 24-hour policy, and the Reading Room, together provide one convenient study spot.  Perhaps there is a coffee shop in Oxford that remains open late and I Just haven't discovered it yet, or maybe only pubs and bars serve the late night folk.

I wonder if the coffee crowd is not as large here as it is in the US.  Early risers and night owls supply the major revenue for coffee shops in the US.  With the numerous historic pubs in Oxford, I suppose the economy is doing just fine and will not adopt the US system of late night coffee shops.  Or perhaps the libraries are the only locations set aside for studying.
