State bookmobile service has evolved into an extensive system of interlibrary loans (ILL) and robust statewide delivery service. From July 2013 to June 2014, 6.7 million ILL items circulated between Massachusetts's libraries, predominantly through Optima, a courier delivery service, for the Massachusetts Library System.
