The library is such a great, yet often overlooked, resource.
My latest "discovery" is that the library has a huge cookbook selection. I can go, check out some cookbooks, try some of the recipes, make sure they work and that I like the results, and then return them. That way, if I like the book and the recipes, I can go buy it. If I don't like the book ... well that's OK because it isn't taking up precious shelf space in my personal "library". And, don't even get me started about how convenient it is to search the library catalog via the internet to see which library has the book before you head out. They've come a long way from those typewritten card catalog files.
This particular library, the Harold Washington Library, also has a lot of art, interesting designs, and architecture. This isn't a hallway to the window. It's more like a long narrow window sill. I liked how the windows from the building across the street lined up so well (at my eye level -- someone taller or shorter wouldn't get the same view) and all the different angles.
