The Oracle Public Library (OPL) is a unique non-profit organization staffed entirely by volunteers and financed with donations. It was started as a reading room in 1903 and has grown to 2,600 square feet.

Through its property tax system, Pinal County gives Oracle Public Library a limited account to purchase books, but no money. In order to pay water, gas, electric, phone, maintenance on the building and keep the grounds in good condition, OPL depends on donations from the friends, families and citizens of Oracle.

OPL is staffed by 25 to 30 volunteers. These volunteers do many things to keep the library open and operating such as check books in and out, help patrons locate books and information, file, catalog books, repair books, keep the shelves in order, attend meetings and seminars, maintain the inside and outside of the building, etc.
