Reports the findings of a study which examined the question of submitting error reports to OCLC for the purpose of database quality control, and describes ENHANCE, a program that would provide online error correction capability for member libraries. Eight references are cited. (FM)

Reports a survey conducted by the Bibliographical Center for Research to determine the extent of variations for entering local data on the part of BCR OCLC libraries. The results are presented along with a discussion of alternative practices and their impact on the processing of OCLC tapes. References are included. (Author/RAA)

Describes an interface mechanism called "complex view support" to be used with a relational database system (RDBS) in supporting increasingly complex distributed environments in automated library systems. The interface system refers queries to multidimensional tables as well as to flat tables on RDBS and is shown to efficiently support…

Describes the design and operation of four software packages, or macros, written in the programing language of Microsoft's EXCEL for use on the Macintosh computer for data manipulation and presentation used in educational research. Reordering tabulated data, reversing the scoring of tabulated data, and creating tables and graphs are explained.…

Evaluates the performance of different methods of data compression coding in several situations. Huffman's code, arithmetic coding, fixed codes, fast approximations to arithmetic coding, and splay coding are discussed in terms of their speed, memory requirements, and proximity to optimal performance. Recommendations for the best methods of…

Describes a procedure for using a subscription agent's computerized facilities to facilitate a subscription profile by providing initial serial listings for use in a library user survey, manipulating obtained data, and producing listings that identify resulting serial titles and costs according to requesting disciplines. (Author/MBR)

Describes a program for enrollment projections in sufficient detail to communicate the output generated and techniques utilized. Interspersed with the text are 14 tables. (MLF)

The LOTUS 1-2-3's special database management operations are used by school budget officials to display data in a variety of ways to assist their decision making. (MLF)

Describes a computer program designed to manage statistics about online searches which reports the number of searches by vendor, purpose, and librarian; calculates charges to departments and individuals; and prints monthly invoices to users with standing accounts. (CLB)

Introduces the multicharacter trie as an index structure that can improve the time needed for retrieving full-text materials stored on CD-ROMs. The advantages of this structure compared to other structures are described, and experimental results comparing it to the widely used B+ tree and other structures used for full-text retrieval are…

Describes VisiCalc, a programmed package for use with the Apple II microcomputer and discusses the use of this program for two library tasks--statistical analysis and budgeting. System features are described in the context of these applications and six tables illustrating system output are appended. Additional resources are listed. (RAA)

Developed by the U.S. Bureau of Labor Statistics, TPL is a flexible natural language computer package that can be used to simplify the preparation of tables of data for annual library reports. Data on interlibrary loan transactions are used to construct sample tables illustrating program features. Two references are listed. (RAA)

Introduces two data distortion methods (Frequency-Imposed Distortion, Frequency-Imposed Probability Distortion) and uses a Monte Carlo study to compare their performance with that of other distortion methods (Point Distortion, Probability Distortion). Indications that data generated by these two methods produce accurate statistics and protect…

Described are computer assisted instruction exercises designed by a college professor to help undergraduate psychology students acquire fundamental skills in data collection--recording the data, using tables and graphs, and recognizing functional relationships. (RM)

Describes a program written in VS BASIC which was created for the online tabulation, summarization, and display of information on collection size for an academic library and compares its performance with that of SAS (Statistical Analysis System). Nine figures compare tables produced by the two systems, and two references are given. (RAA)
