Thanks for your email. We agree that the 6th floor could be better used. We are continuously looking at the spaces available to us and try to repurpose them to meet the needs of our users. We will eventually look at the 6th floor, but it won't be for some time yet. As you will see at the following link, most of the rest of Mills library is wireless (http://library.mcmaster.ca/mills/study.htm).
The doors on the 2nd floor are only used when the Learning Commons is open and the rest of the library is not. It is possible that this might change in the future, if the library were funded to remain open 24 hours per day. Please note a 24/7 pilot to keep the Learning Commons open during the spring exam period will begin on April 9th and run to April 28th.
