AERE Library Computer Based Loans System—Coblos

The off‐line computer based loans system developed in AERE Library between 1968–70 has been operational since 1 December 1970. The system covers loans, discharges, reservations, borrower searches, etc. (ten types of transaction in all), for four kinds of document—reports, periodicals, books and pamphlets. The system uses two teletypewriters in the Library to produce 8‐track punched paper tape which is input to the Harwell IBM 360/75 computer. The principal output consists of printed loans lists, reissue and recall notices, diagnostics, error messages and statistical information. In addition to an improved control of loans, the system has already led to a saving in clerical effort; full benefits should be realised in 1971/72.
