Discusses the multilevel information system (MLIS), a retrieval system that integrates functions typical for database management systems and retrieval-oriented systems and provides several levels of data accessing, each developed for a different class of users. Twenty-two sources are cited. (FM)

Computer routines designed to determine if a song already exists in a song file data base are described. Written in FORTRAN IV, SONG FILE DATA MATCH compares the note sequence of songs in the data base and the one to be added to it. Information is then presented to the user which analyzes the sequence of notes and compares them to other songs.…

This paper examines some of the finding aids (e.g., information that provides insight into a group of records in an archival collection) currently used or being developed by the National Archives and Records Administration (NARA). It explores their practicality and whether and how they can be improved. In addition, the paper analyzes the factors…

The second of four volumes in a series describing the basic documentation practices involved in the initial setting up and subsequent operation of an information-library organization to provide defense-aerospace scientific and technical information services, this manual consists of three sections. "Data Recording and Storage," by J.…

During the 1971-72 pilot test of the Southwest Regional Laboratory's (SWRL) Instructional Management System (IMS), three alternative procedures were used to gather data within the classroom, transmit those data to SWRL for processing, and send IMS output to the appropriate recipients in the schools. ComSys 3--one of the three…

The development of microform-based information storage and retrieval systems is discussed, and the comparative advantages and costs of various approaches are considered. A proposed computer system--Archival Information Dissemination System (AIDS)--to support microform retrieval is outlined. Included are diagrams of sequential flows of information…
