Exam periods are right around the corner, and we want to make sure you are informed about access to the libraries during midterms and finals this semester.  The updates below outline access policy changes happening throughout the semester for several libraries.  The new Study Space Open Now page shows you which libraries are currently open in real time (bookmark that page!), and the Library Hours page provides a calendar view for each library’s hours of operation.  For a full list of library facilities, please visit the Study Spaces guide.  Also, don’t forget about the Room Scheduler to book a room for practicing presentations, holding group meetings, etc.

• The Science & Engineering Library will begin study hall hours until 3 a.m. on October 4, Sundays through Thursdays, running through the end of the semester. During the weekend of midterms and finals, the study hall hours will be extended to Friday and Saturday.
• During the last four weeks of the semester, the Lehman Social Sciences Library will hold study hall hours until 4 a.m. seven days a week.
• Butler Library will continue to be open for study 24-hours a day, seven days a week during the semester.  During the last four weeks of the semester, 24-hour study will be extended to reading rooms on the 5th and 6th floors.
• During midterms and finals, the Business & Economics Library will be open to all graduate students, faculty, staff, and to undergraduate Economics majors only. Others who need library resources or research assistance found only at the Business & Economics Library may request access and assistance at the circulating desk.  During the Fall semester, this policy will apply October 7-21 and December 2-18.  The Business & Economics Library is open to all Columbia affiliates other times throughout the semester.
