The Old Colony Library Network (OCLN) is a consortium of 28 member libraries located on the South Shore of Massachusetts in the United States. OCLN membership includes 26 town and city libraries and two academic libraries. OCLN's cooperative approach enables member libraries to provide services that they would not be able to afford separately. OCLN was founded in 1984 and is incorporated in Massachusetts as a 501(c)3 corporation. OCLN is recognized as a charitable organization by the Massachusetts Attorney General's office.
