AMA (Automatic Message Accounting), computerized telephone call accounting articles reprinted from Bell Laboratories Record, ca 1953. Automatic message accounting (AMA) provides detailed accounting for telephone calls.

The need to record the time and phone number of each long-distance call was met by electromechanical data processing equipment. Articleas include: "Code Patterns in Telephone Switching and Accounting Systems" by J.W. Dehn; "The AMA Tape Perforator" by P.B. Drake; "The AMA Assembler" by Glen C. Drew; "The AMA Computer" by A.E. Hague; "Tape-to-Card" Converter" by W.B. Groth; and much more. 138 pages. Halftones, diagrams, Pictorial stiff paper, spiral binding. Triffle rubbed.
