The Colorado Plan for Library Development is intended to serve as a general guide for the development of library service in the state. The Plan, which includes a number of recommendations from the Nelson Associates Report of 1965 (ED 020 746), was drafted by a committee representing the Colorado Council for Library Development, the Colorado Library Association, and the Colorado State Library, and reflects the thinking of academic, school, public, and special librarians. There is a brief discussion of th e current status of Colorado's academic, public, school, and special libraries. The primary objectives of the Plan are to (1) change the Colorado Library Law of 1947 to make implementation of the Plan possible, (2) redefine the role of the Colorado State Library, (3) provide for the legal establishment of public library systems, (4) establish a complete state-wide reference service, (5) establish standards for library operations, (6) define and implement the roles of the several types of libraries, and (7) establish study groups to develop state-wide programs within the framework of the Plan. The role of the State Library, and plan of operation, and the financing of the state Plan are also discussed. (Author/CC)
