The Periodical Room on Floor 2 is a designated Quiet Zone, for users requiring an absolute minimum of noise and distraction. Users are asked to refrain completely from conversations (including cell phone), and no group study is allowed.
The rest of the library is considered semi-quiet study area, with conversations allowed as long as voices are kept low. Individual carrels in secluded parts of the building, such as the perimeters of the book stacks on all floors and tiers, tend to be relatively quiet. Open areas with large study tables tend to be less quiet.
