Come check out the SED Undergrad Student Gov't meetings every other Monday at 7:30! First meeting on Monday, September 10th!
Check out the Sustainability Resources Center located in the lower level of SED. It has a wide range of books and dvds, and it's also a great place for clubs to meet!
The library in the basement is full of children's books and is a little-known study space. Plus, it has it's own Keurig coffee machine- just bring a mug!
