Personal information management (PIM) is a research field that examines the activities by which users save, organize and retrieve personal information items. PIM is a one of the essential new literacies for learners in the 21st century. This paper reports results from a pilot study that explored PIM practices and strategies of K-12 students, on…

Passwords have the distinction of being the most widely-used form of authentication--and the most vulnerable. With the dramatic increase today in the number of accounts that require passwords, overwhelmed users usually resort to creating weak passwords or reusing the same password for multiple accounts, thus making passwords the weakest link in…

Part One, Automatic Content Analysis contains: "Content Analysis in Information Retrieval;""The 'Generality' Effect and the Retrieval Evaluation for Large Collections;""Automatic Indexing Using Bibliographic Citations" and "Automatic Resolution of Ambiguities from Natural Language Text." Part Two, Automatic…

This review of the literature on full-text databases provides information on search strategy, performance measurement, and the benefits and limitations of full text compared to bibliographic database searching. Various use studies and uses of full-text databases are also listed. (21 references) (LAE)

An initial attempt at presenting a coherent approach to the design and analysis of file structures include a discussion of the relative effeciency of different file implementations as a function of usage statistics. The fundamental differences between item and descriptor-organized files are discussed in terms of input-output requirements.…

As the fourteenth report in a series describing research in automatic information storage and retrieval, this document covers work carried out on the SMART project for approximately one year (summer 1967 to summer 1968). The document is divided into four main parts: (1) SMART systems design, (2) analysis and search experiments, (3) user feedback…

System Development Corporation's (SDC) exploration of microform state-of-the-art and current research reveals developments which will be applicable to the requirements of many small Department of Defense (DoD) users and similar facilities in the next two to five years. The study's survey of the small user population reveals a variety of user…

Search theory, originally developed for antisubmarine search, is applied to the scanning of library shelves for books of interest, or of a computerized abstract catalog for items of immediate application. Procedures optimizing the information to be found are discussed, as well as methods whereby the operational parameters can be measured. The…

The philosophy of a systems approach to the design of information storage and retrieval systems is suggested in which the computer is recognized in its proper perspective as a powerful and effective alternative tool. (Author)

Subcommittees of the Committee on Information Hang-Ups concern themselves with attempting to break down the barriers between the user and the information he seeks. This report discusses the problems encountered with the use of microforms and especially with the use of microfiche. (Author)

It is the purpose of this study to provide fresh insight into the nature of library problems by systematically studying the question of size in various information contexts. In the introduction, the role that size plays from the user's point of view is illustrated. In the following sections, a study of the card catalogue, the classification system…

This study revealed that the use of the NLM Documents Section is extremely modest. A total of 144 inter-library loan requests were filled by the Section in the months of January and February, 1972; most of these were from Government agencies. The study investigator recommended that: (1) the collection should be maintained by the NLM; (2) that…

A simulation study of library-based information retrieval systems is described. Basic models for each of several important aspects are presented: (1) user behavior, emphasizing response to quality and delays in services; (2) the scheduling of services and the organization of the machine-readable files; and (3) the distribution of conventional…

Heavy emphasis was placed on experiments, and interpretation of experimental results. A set of experiments was designed to yield quantitative information on how the experimental subjects used the full-text-access system, why they used it and how effective it was. A detailed report of work on this topic to date is presented. The in-depth analysis…
