Orthographic Error Patterns of Author Names in Catalog Searches (p.93-101)
RENATA TAGLIACOZZO, MANFRED KOCHEN, AND LAWRENCE ROSENBERG
An investigation of error patterns in author names based on data from a survey of library catalog searches. Position of spelling errors was noted and related to length of name. Probability of a name having a spelling error was found to increase with length of name. Nearly half of the spelling mistakes were replacement errors; following, in order of decreasing frequency, were omission, addition, and transposition errors.
The RECON Pilot Project: A Progress Report (p.102-114)
HENRIETTE D. AVRAM
A synthesis of the progress report submitted by the Library of Congress to the Council of Library Resources under an Officer's Grant to initiate the RECON Pilot Project that gives an overview of the project and the progress made from August-November 1969 in the following areas: training, selection of material to be converted, investigation of input devices, and format recognition.
Comparison of LC Proofslip and MARC Tape Arrival Dates at the University of Chicago Library (p.115-121)
CHARLES T. PAYNE AND ROBERT S. MCGEE
A comparison of arrival dates of 5020 LC proofslips and corresponding MARC magnetic tape records reveals that four-fifths of the MARC records were received the same week as, or earlier than, the proofslips.
Levels of Machine Readable Records (p.127)
RECON WORKING TASK FORCE: HENRIETTE D. AVRAM, CHAIRMAN; RICHARD DE GENNARO; JOSEPHINE S. PULSIFER; JOHN C. RATHER; JOSEPH A. ROSENTHAL AND ALLEN B. VEANER
This study of the feasibility of determining levels or subsets of the established MARC II format concludes that only two levels are necessary and desirable for national purposes: 1) the full MARC II format for distribution purposes; and 2) a less complex subset to be used by libraries reporting holdings to the National Union Catalog.
On-Line Serials Systems at Laval University Library (p.128-141)
ROSARIO DE VARENNES
Description of a system, operational since June 1968, that provides control of all serials holdings in nine campus libraries, permits updating of the complete file every two or three days, and produces various outputs for library users and library staff from data in variable fields on disks (listings, statistics, etc.). The program, presently operating on an IBM 360/50 and utilizing an IBM 2314 disk-storage facility and three IBM 226 CRT terminals, is written in IBM System/360 Operating System Assembler Language and in PL/I; it could encompass a file of no more than 10 million records of variable length limited to 127/255 characters and subdivided in 25 or fewer fields.
LC/MARC on MOLDS; An Experiment in Computer-based Interactive Bibliographic Storage, Search, Retrieval, and Processing (p.142-165)
PAULINE ATHERTON AND KAREN B. MILLER
A project at Syracuse University utilizing MOLDS, a generalized computer-based interactive retrieval program, with a portion of the Library of Congress MARC Pilot Project tapes as a data base. The system, written in FORTRAN, was used in both a batch and an on-line mode. It formed part of a computer laboratory for library science students during 1968-1969. This report describes the system and its components and points out its advantages and disadvantages.
