A short list of Millbury-centric or photography-centric (or better yet both) books I enjoy.

Heart of the Commonwealth: A photographic portrait of Worcester & Central Massachusetts (late 2012)
Prolific Millbury photographer Edd Cote played photo editor (quite effectively, I might add) for this vivid coffee table-style photo book showcasing the people, places, and culture of Central Massachusetts. The hardcover version ($32, shipped) contains a good number of images taken in Millbury and is a nice snapshot of modern culture in this part of the state. A full electronic version can be found here.
