130 St. George St.
While I was in Toronto I went to a lot of different libraries, so be prepared for several weeks of pretty similar posts about using the internet. But first! A tale of not using the internet.
At the main U of T library I asked if I could get a guest account to use the computers. I am a graduate student, albeit at another library, but this apparently doesn't matter as I was told "no". But there were some computers open to the public and I could get an account for one of those.
I got an account, trekked upstairs and discovered that of the four computers available for public use, one was broken, and the other three were occupied. There appeared to be no way to sign up for a time slot, no way to know how long someone had been on a computer (or what the time limit was), and at least one other person waiting, so I left. Disappointing. Apparently you can't even get into the stacks without a library card. Lame.
