Two basic data processing concepts are described: data elements (consisting of bits, bytes, fields, records, and files) and binary characters (standards, hex value, and extended character sets--Greek letters, superscripts, and subscripts). Use of machine-readable data in the OCLC-MARC database is noted. (EJS)

Compares pricing of seven CD-ROM-based public access catalog systems for libraries of diverse sizes and groupings. Other features of the systems are outlined in the broad areas of database preparation, indexing, database updates, hardware, information retrieval, library controlled elements, interlibrary loan, reports, user support, future…

BiblioFile Intelligent Catalog is a CD-ROM-based public access catalog system which incorporates graphics and sound to provide a multisensory interface and artificial intelligence techniques to increase search precision. The system can be updated frequently and inexpensively by linking hard disk drives to CD-ROM optical drives. (MES)

Defines and describes the components and functions that constitute a microcomputer--bits, bytes, address register, cycle time, data path, and bus. Characteristics of 8-, 16-, and 32-bit machines are explained in detail, and microprocessor evolution, architecture, and implementation are discussed. Application characteristics or types for each bit…

Introduces concepts of server security and includes articles and sidebars of firsthand accounts of consequences of not devoting enough time to security measures. Outlines the following factors to consider when evaluating a server's risk potential: confidentiality/reproducibility of the data; complexity of the system; backup system and hardware…

Discusses the advantages of parallel processor computers in terms of expandibility, cost, performance and reliability, and suggests that such computers be used in library automation systems as a cost effective approach to planning for the growth of information services and computer applications. (CLB)

Describes ACCESS PENNSYLVANIA, a statewide program structured around school libraries which has two objectives: (1) production of a union catalog to facilitate resource identification and retrieval, and (2) development of automated support capabilities within the libraries served by the project. The CD-ROM microcomputer technology used, Le Pac, is…

Presents results of survey of procedures to handle the circulation of unbound periodicals in 232 public and academic libraries using four major turnkey automated circulation systems. Methods used are described (use of machine-readable symbol attached to issue) and procedures developed at the Eastern Washington University Library are explained in…

In order to determine the feasibility of offering free online searches to undergraduates at Texas A&M University's Evans Library, free searches were offered to selected technical writing classes. Student evaluation of the searches are provided and ways to make the service available to undergraduates are suggested. Ten references are cited.…
