Thanks for your comments.
We agree it can be quite noisy on the 2nd floor, so we made some changes over the Reading Week. More information can be found on our News Blog @ http://library.mcmaster.ca/news/5618.
All carrels from the 1st floor were moved to the north side of the lower level.
This area has now been designated as a Quiet Study Area.
Signs will be posted in the next day or so.
Recognizing that the 2nd floor is quite noisy we expect this now to be used more as a Group Study area.
Silent Study space remains available on the 3rd floor.
We hope you find this zoning of study space meets your needs!
