The Minuteman Library Network (MLN), founded in 1984, is a consortium of 41 public and academic libraries in the MetroWest and southern Middlesex County areas of eastern Massachusetts, US that share resources, patrons and services. The Network has over 6 million items and over 680,000 cardholders. Resources are shared. People who live, work, or study in Massachusetts are eligible for a card, which can be used to borrow items from Minuteman libraries.

The Cambridge Public Library (CPL) in Cambridge, Massachusetts consists of a unified city-wide system maintaining: a main branch, of notable aesthetic architectural value, plus a further six localized branches sited throughout the city. Having evolved from the Cambridge Athenaeum, the main library branch was built at its present site in 1888. The main library most recently underwent renovation, and a modern building addition significantly expanded the overall branch in 2009. Thus, it greatly increased the branch's area, more than tripling its square footage.
