Boston's Orange Line, by Andrew Elder and Jeremy C. Fox. This is a collection of black-and-white photos, going back to the start of the old elevated orange line, with captions. This was for the "explore Boston history" square on the BPL summer reading bingo. If I'd noticed the "images of rail" series title, I wouldn't have borrowed this book. The captions are just about enough to confirm that there's more than enough to be said on the subject to make a book, but this isn't. This has a disjointed discussion of the lengthy "realigmnent" of the orange line to its current route, and a couple of paragraphs on the decision not to run an 8-lane interstate through the middle of Boston and Cambridge, and no suggestion that anything similar had happened elsewhere. Ah, well.

There are suggestions on the library website for some of the squares (including "with a green cover"), but not this one. Searching the catalog for "Boston histpry" got me this, along with, among other things, a book about the Big Dig, a book about the Great Molasses Flood (which is at least mentioned in this, with a picture of damage to the orange line), and Hawthorne's The Scarlet Letter.
