I've tried to group them so that the changes of one office over time can be seen. Therefore, Winter Hill, a reincarnation of North Somerville, is listed following that office rather than in a more alphabetical fashion. Hopefully, it will make some sense.

If a listing is in bold, I don't have one in my collection. I am interested in acquiring more Cambridge and Somerville material, even if I already have some in my collection--I'm particularly interested in Harvard related pieces. Please let me know what you have!

The listing below and the rarity factors come from Merolla and Crowther's Post Offices of Massachusetts. While the scarcity levels of some of these seem high, that doesn't always translate to a high price. The MA book tends to be rather more liberal in the assignment of higher scarcity numbers than most other states. Also keep in mind that at the turn of the century Cambridge was one of the 50 largest cities in the United States!
