An Automated Music Programmer (MUSPROG) (p.1-9)
DAVID F. HARRISON AND RANDOLPH J. HERBER

A system to compile programs of recorded music for broadcast by the University of Iowa's radio stations. The system also provides a permanent catalog of all recorded music holdings and an accurate inventory control. The program, which operates on an IBM 360/65, is available in FORTRAN IV, COBOL and PL/I, with assembly language subroutines and external maintenance programs.

High School Library Data Processing (p.10-19)
BETTY FLORA AND JOHN WILLHARDT

Planning and operation of an automated high school library system is described which utilizes an IBM 1401 data processing system installed for teaching purposes. Book ordering, shelf listing and circulation have been computerized.

File Organization of Library Records (p.20-30)
I.A. WARHEIT

Library records and their utilization are described and the various types of file organization available are examined. The serial file with a series of inverted indexes is preferred to the simple serial file or a threaded list file. It is shown how various records should be stored, according to their utilization, in the available storage devices in order to achieve optimum cost-performance.

A Fast Algorithm for Automatic Classification (p.31-48)
R. T. DATTOLA

An economical classification process of order n log n (for n elements), which does not employ n-square procedures. Conversion proofs are given and possible information retrieval applications are discussed.
