From the Williams College Music Department Virtual Tour page for Goodrich:
Goodrich Hall is a Gothic revival, rustic limestone structure built in 1859 to serve as the College Chapel, Alumni Hall and classrom building... The Goodrich Hall is the only student operated building on campus. Students are responsible for managing and coordinating the use of the space.
Another good resource is the Williams College Campus Life Student Activities Goodrich Hall information page which has, among other resources, a Coffee Bar menu, a listing of hours, a form for scheduling activities at Goodrich, policies, and other useful information.
Goodrich Hall is a well-loved space with a variety of functions. Depending on when you visit it, you are likely to find students getting breakfast points at the coffee bar, hanging out, checking e-mail, or studying into the wee hours of the morning (or falling asleep in the comfy leather armchairs), Contra Dances, Gospel Choir concerts, Sankofa performances, First Fridays, Cap and Bells productions, a cappella concerts, movie showings, open mic nights, and much more.
According to the Williams College Property Book, Goodrich Hall has over 10,000 square feet of usable space.
Since the demolition of Baxter Hall, Goodrich Hall has been a good headquarters for the administration of the semiannual overight Williams Trivia contest.
