Library Hours

Contact Me

I have listed some of my contact information below. Please feel free to come visit me at the library or after class.


At the main research desk:

Monday, 6:00 p.m. - 11:00 p.m.

Wednesday, 1:00 p.m. - 3:00 p.m.

If these hours don't work for you, I would be happy to set up an appointment.  You are also free to stop me whenever you see me in the library to chat about your research needs. 


You can email me at any time, and I will get back to you as quickly as possible.



You can call me during library hours, or leave a message and I will call you back.
