Actually, the Portland Public Library no longer has it. I was in there a few months ago to get it, and we found that it had been stolen! (Good that someone wanted it, I guess, but still...) I was told that they would re-order it, but I just called for an update and the woman said it hadn't been yet. BUT, she found two other copies available through inter-library loan. I'll probably ask for one (I couldn't right now because I didn't have my library card handy), but you can ask for the other, powerhouse. Call the reference section (871-1700) and say that you were told it was available through Maine Infonet.
I have also written an article on one of my websites about riding safely in traffic, with some links to other places,
here. You might find it useful, and I very much welcome constructive feedback on it.
