The purpose of this survey is to identify and describe existing and contemplated projects in the Smithsonian Institution which make use of non-conventional means to store and retrieve information. These techniques range from electronic machine processed to a simple visual, color-coded system or a key-sort device. The 49 projects investigated were…

Response time of on-line document retrieval systems is analyzed. Linear and inverted file organizations are considered and their response times are evaluated. (Author)

The characteristics of the Intrex subject/title inverted file are analyzed. Basic statistics of the inverted file are presented including various distributions of the index words and terms from which the file was derived, and statistics on stems, the file growth process, and redundancy measurements. A study of stems both with extremely high and…

INDEX, an interactive retrieval program developed at Pepperdine University, is described. It is easy to use and maintain, locates sources of information from a general description of the information needed, requires only a modest investment of time, and is widely applicable. (MLW)

The report summarizes work done in the study of measures for the effectiveness of the performance of large file systems. It consists of six sections: An "Introduction and Summary" which describes the background for the study, the approach taken in it, and summarizes the results; A discussion of the "Forms of Input", which characterizes the basic…

Review of office filing facility filing and retrieval mechanisms for unstructured and mixed media information focuses on free text methods. Also discussed are the state of the art in handling voice and image data, problems with searching text surrogates to implement free text content retrieval, and work of Project Minstrel. (Author/MBR)

Until recently, the emphasis in information storage and retrieval systems has been towards batch-processing of large files. In contrast, SHOEBOX is designed for the unformatted, personal file collection of the computer-naive individual. Operating through display terminals in a time-sharing, interactive environment on the IBM 360, the user can…

In four conference presentations newspaper librarians presented information about their photograph storage and retrieval operations. They discussed picture sources, selection and weeding, picture evaluation, picture quality, ways photos are used, filing methods, source books for illustrative material, file subject coding, ways of dealing with…
