Libraries (Hosted Feature Layer)

Public and some special libraries currently registered with the Massachusetts Board of Library Commissioners (MBLC). This layer also includes a small subset of "special" libraries as categorized by the MBLC whose main function is to operate as a library. Many schools, hospitals, trial courts, law offices, historical societies, museums, private companies and other public and private institutions house libraries in addition to their primary operations. They are not included in this data layer.本数据集涵盖目前已在美国马萨诸塞州图书馆委员会（Massachusetts Board of Library Commissioners, MBLC）完成注册的公共图书馆，以及该委员会划定分类的、以图书馆运营为核心职能的一小部分‘特殊’图书馆。诸多学校、医院、初审法院、律师事务所、历史学会、博物馆、私营企业及其他公共与私营机构，虽在自身核心业务之外均设有附属图书馆，但此类图书馆并未被纳入本数据图层。
