My office is located at the back of the library on the first floor near the Teaching Materials stack (L call number). If you get to the Academic Support desk, you've gone just a few feet too far.
I generally work 8:30 am - 4:30 pm Monday - Wednesday, 1:00 pm - 9:00 pm Thursdays, 8:30 am - 4:30 pm Friday. I am at the Reference Desk on Thursday evenings (6:00 - 9:00 pm) as well as one or two afternoons each week. Check my calendar to verify my availability.
