There are lots of great online sources of information on In The Skin of a Lion. One of the most fascinating webpages you'll find on the novel is this one from the City of Toronto Archives. Here you can see some of the actual photographs described in the novel, including the picture of two men shaking hands in the tunnel underneath Lake Ontario and the one of the cyclist darting across the Bloor Street Viaduct on the day it was christened and opened to the public.

You'll see a period photo of the Harris Filtration plant, the "Palace of Purification" on the City of Toronto Archives site, but this plant still exists and it has its own website where you can actually do a virtual tour of the complex. There's also an aerial shot here.

I've already directed you to the articles i have on electronic reserve in the library. Here's another interesting article that focuses on the influence of John Berger's influence on In the Skin of a Lion and looks at the book as a "cubist novel."
