A book of yellow pages showed up at our door the other day. Fewer of those arrive with each passing year, but arrive they do. It’s a little hard to remember when they were essential reference works for the house, but so they were.

And like any good reference work, it was good to browse through them occasionally. Almost 30 years ago, in Nashville, I remember thumbing through one edition – it must have been an “official” one by one of the Baby Bells – and coming across a quarter-page ad for a roofing contractor that promised DEATH TO ROOF LEAKS, complete with skull-and-cross illustrations. Who knows, maybe the Republican Guard was getting into the roofing business in those days.

The edition we just got covers a big chunk of the Northwest suburbs. It has some standard reference information in the front, including a map of North American area codes. The metro New York and Los Angeles insets are very crowded with numbers, and metro Chicago could probably stand its own inset, too, but doesn’t get one. Are there still any states with one area code? Yes. Quite a few, actually: Alaska, Delaware, Hawaii, Idaho, Maine, Montana, New Hampshire, North Dakota, Rhode Island, South Dakota, Vermont, and Wyoming.

Next are “City, County, State and U.S. government offices” pages, which were blue in some yellow pages, but white in this one. These are always good for finding some oddities, such as a toll-free number for information on adopting wild horses and burros, a number of the inspector general of the Peace Corps, and a general information number for St. Lawrence Seaway Lock Operations.

My packratish nature won’t let me throw it away for a while. But I doubt that I’ll need it to use it to call the St. Lawrence Seaway or anywhere else.
