Headcounts from the April week demonstrate that at 11:00 p.m., 12:00 a.m., and
1:00 a.m., headcounts were more than two times higher on Sunday, Monday,
Tuesday, and Wednesday nights than on Thursday nights. The 2:00 a.m.
headcounts show that even after our final closing announcement each night,
we still had some users present.
Headcounts for the last three hours of Friday and Saturday nights, when we
close earlier than the rest of the week, show fewer users present than Sunday
through Wednesday, and more than on Thursday. After the final closing
announcements on Friday and Saturday nights, no users remained in the library.
During final exams in May, student workers counted users at 1:00, 3:00, and 4:00
a.m. (Because only one student worker worked on May 4 and May 9, 1:00 a.m.
and 3:00 a.m. headcounts were not possible on those dates.) The available 1:00
and 3:00 a.m. headcounts demonstrate that in some cases, Olin contained a large
number of users during the late-night hours. 4:00 a.m. counts show that after the
final closing announcements, users remained in the library:
User Activity during Headcounts
While performing the April and May headcounts, Olin student workers made
note of what users were doing: studying, using computers and printing,
browsing the collections and using the library catalog computers, sleeping,
and walking. We used the term “studying” somewhat loosely to apply to any
