TL;DR: The technique operates on the prin cip le of taking two alphabetic characters frequently used in combination and replacing them with one unused special character cod e, which has enabled the ILO to achieve a rate of compression of 43.5 % on a data base of approximately 40,000 bibliographic records.
Abstract: Description of a t ec hnique for compressing data to be placed in computer auxiliary storag e. The technique operates on the prin cip le of taking two alphabetic charact e rs frequently used in combination and replacing them with one unused special character cod e. Such une-for-two replacement has enabled th e ILO to achi eve a rate of compression of 43.5 % on a data base of approximately 40,000 bibliographic records.

TL;DR: An experiment testing utility of truncated search keys as inquiry terms in an on-line system was perform on a file of 16,792 title-only bibliographic entries, yielding eight or fewer entries 99.0% of the time.
Abstract: An experiment testing utility of truncated search keys as inquiry terms in an on-line system was perform e d on a file of 16,792 title-only bibliographic entries. Use of a 3,3 key yields eight or fewer entries 99.0% of the time.

TL;DR: A description of a highly cooperative SDI system develop e d by the Library, University of Saskatchewan, and the National Science Library that will permit searching over all subject areas repres e nted by the English language monographic literature on MARC is provided.
Abstract: Subscriptions to the Library of Congress' MARC tapes number approximately sixty. The uses to which the weekly tapes have been put have been minimal in the area of Selective Dissemination of lnformation (SDI) and current awareness. This paper reviews work that has been performed on hatched retrieval/dissemination and provides a description of a highly fl exib le cooperative SDI system develop e d by the Library, University of Saskatchewan, and the National Science Library. The system will permit searching over all subject areas repres e nted by the English language monographic literature on MARC.

TL;DR: An on-line circulation system developed at a relatively small university library demonstrates that academic libraries with limit e d funds can develop automated systems utilizing parent institution's computer facilities in a time-sharing mode.
Abstract: An on-line circulation system developed at a relatively small university library demonstrates that academic libraries with limit e d funds can develop automated systems utilizing parent institution's computer facilities in a time-sharing mode. In operation since September 1968, using an IBM 360/50 computer and associated peripheral equipment, it provides control over all stack books.

TL;DR: It is suggested that automation of serial r e cords is smaller than has been assumed to date and that such an automated syst e m c an be economically justifiable in a library of r e latively mod e st size.

TL;DR: An entry/title compression code is proposed which will fulfill the following requirements at the Library, University of Saskatchewan: 1)Entry/title access to MARC tapes; 2) entry/ title access to the acquisitions and cataloguing in-process file; and 3) entry /title duplicate order edit within the acquisitionsand cataloguingin-processfile.

The study which produced the code and applications for the code are discussed.

TL;DR: A recursive presentation of a communication format is discussed and a form of pertinent notation proposed that permits presenta tion of an interchange format in more general terms than heretofore published, and expands application possibilities.

TL;DR: A progress report on the RECON Pilot Project submitted by the Library of Congress to the Council on Library Resourc es covering the period October 1970-May 1971 is given in this paper.
Abstract: Synopsis of three progress reports on the RECON Pilot Project submitted by the Library of Congress to the Council on Library Resourc es covering the period October 1970-May 1971. Progress is r e ported in the following areas: RECON production, foreign languag e editing test, format recognition, microfilming, input d ev ic e s, and tasks assigned to the RECON Working Task Force.

TL;DR: D esc rib es a method for preparing personal names already in machine read able form for processing by any standard computer sort program, determin ing filing order insofar as possibl e from normally available information rather than from special formating.
Abstract: D esc rib es a method for preparing personal names already in machine read able form for processing by any standard computer sort program , determin ing filing order insofar as possibl e from normally availabl e information rather than from special formating . Pr e fix recognition is emphasized; multi word forename entries are a problem area. Provision is made for an edit list of probl e ms requiring human decision. Possible extension of the method to titles is discussed.
TL;DR: TRIPS (TALON Reporting and Information Processing System) is an interactive software system for generating reports to NLM on regional medical library network activity and constitutes a vital part of a network management information system (NEMIS) for the South Central Regional Medical Library Program.
Abstract: TRIPS (TALON Reporting and Information Processing System) is an interactive software system for generating reports to NLM on regional medical library network activity and constitutes a vital part of a network management information system (NEMIS) for the South Central Regional Medical Library Program. Implemented on a PDP-lOfSRU 1108 interfaced system, TRIPS accepts paper tape input describing network transactions and generates output statistics on disposition of requests, elapsed time for completing filled requests, time to clear unfilled requests, arrival time distribution of requests by day of month, and various other measures of activ ity andjor performance. Emphasized in the TRIPS design are flexibility, extensibility, and system integrity. Processing costs, neglecting preparation of input which may be accomplished in several ways, are estimated at $.05 per transaction, a transaction being the transmittal of a message from one library to another.
