In search of a legend

During my last massive effort to gather my comp material, I made a lovely, colour- and symbol-coded list indicating which books and articles I had, which ones were available to take out of the library, which were short enough to be photocopied at the library, which I would have to order in through inter-library loan, and which I'd have to hunt down through second hand stores. It's a great list--I have every item covered. The only thing I didn't include was a legend, because I figured I'd remember.

Right.

I fervently hope truly believe that if I sit down and stare at the list long enough, eventually it will come back to me. When it does, I am going to write down what every one of those colours and symbols means.
