As I am sure you are aware the use of the library has changed dramatically over the last few years, and very few areas are now quiet. One thing we have attempted to do is to zone the various types of study space in our libraries. We would encourage you to find the space that meets your personal needs the best @ http://library.mcmaster.ca/study-space
Additionally, we have created the Guidelines Governing Personal Behavior (http://library.mcmaster.ca/policies/behaviour) which we do expect users to abide by, but it is sometimes a challenge to enforce these guidelines.
