This study of the four adult correctional institution libraries in Maryland is based on background data obtained from a survey questionnaire, conferences with institutional personnel, and tours of the library facilities and education departments. Findings show that although an attempt has been made to organize the libraries, they are still inadequate. Recommendations outline an immediate library development plan for the next two years and a long-range plan to be accomplished within a five year period. The plans involve: (1) establishment of a pilot library demonstration program at the Maryland Penitentiary in 1966, to be supported by a grant for the first two years, (2) creating a supervisory library division in the Maryland Department of Corrections, which would include the appointment of a professional librarian, (3) development of library service in the other three correctional institutions in 1967 and 1968, with funds requested in the Department of Corrections budget, and (4) organization of a library program for correctional camps as soon as it is financially feasible. A detailed library program is outlined for each of the four institution, the Maryland Department of Corrections, and the correctional work camps. The "Objectives and Standards for Libraries in Correctional Institutions, prepared by a committee of the American Correctional Association, is appended. (JB)
