This dissertation presents a novel theory of event memory along with an associated computational model that embodies the claims of view which is integrated within a cognitive architecture. Event memory is a general-purpose storage for personal past experience. Literature on event memory reveals that people can remember events by both the…

The cost of an item of information in a storage system is defined as the sum of an initial cost, a time dependent cost, and a usage cost. Item usage is assumed to follow a simple exponential obsolescence pattern. A decision rule for the economic holding time of an item in storage is derived from the model and based on a policy of minimizing the…

The optimal storage of books by size in libraries is considered in this paper. It is shown that for a given collection of books of various sizes, the optimum number of shelf heights to use can be determined by finding the shortest path in an equivalent network. Applications of this model to inventory control, assortment and packaging problems are…

Most library buildings were built thirty or more years ago. As a result libraries are sharing a common situation. There is little or no room to add more books onto the shelves, and there are odd spaces throughout the stacks which are not being used. Jackson Library, University of North Carolina at Greensboro, faced this challenge and grew space by…

A plan for a library with a storage level in the shape of a flat spiral is presented. The advantages of such a plan include: space saving, easy expansion of the building, an unbroken sequence of shelving, quick access to all books and freedom in the design of the library's other sectors. This plan is especially suited for the research library…

Presents an improved inverted region quadtree variation called Dynamic Inverted Quadtree that is able to support and index a pictorial database. Pattern-searching algorithms are described, and the space needs of Fully Inverted and Dynamic Inverted Quadtrees are analytically compared based on a model of image randomness expressed as a branching…

Examines the intersection of conservation and digital imaging based on guidelines at the Cornell University (Ithaca, NY) library. Discusses the digitization of artifacts; assessing the condition prior to scanning; scanning considerations, including temperature and humidity, lighting, and security; stable storage of artifacts after scanning; and…

Offers a model for academic libraries that bases decisions on CD-ROM cataloging, circulating, and housing on three factors: type of data on a CD-ROM, who will use the data, and how they will use it. Four types of CD-ROMs are discussed: music, reference, data, and CD-ROMs that accompany other materials. (DGM)

Proper cleaning and storage of audiovisual aids is outlined in this brief guide. Materials and equipment needed for first line maintenance are listed, as well as maintenance procedures for records, audio and video tape, film, filmstrips, slides, realia, models, prints, graphics, maps, and overhead transparencies. A 15-item quiz on software…

Develops a cost methodology to use in deciding location, type of access, and type of shelving to augment existing stacks in the library. Library and user costs are included in the model and cost comparisons between alternative strategies are made. Data from a specific case study are used to illustrate the model.

A cost analysis of the problem of growing library collections shows that it is more desirable, economically and academically, to establish regional compact shelving facilities for infrequently used library materials than to discard the materials. This report develops and applies a cost model--based on the Palmour Cost Model--which examines the…

A study of alternative models for establishing a cooperative storage center for little used library materials by the members of the Area College Libraries of Central Pennsylvania (ACLCP) focused on periodicals. Considerations discussed include advantages--lower cost; space for growth and better access to holdings retained in active collections;…

A model based on storage and retrieval costs that determines efficient allocation of materials to different storage regimes in academic libraries is developed. An economically rational basis for determining role of several alternative storage methods which distinguish among materials by expected level of use is offered. Nineteen references are…

Updates a storage cost model for academic library collections by examining how changes in construction costs and circulation costs affect the choices of an alternative book storage strategy. Results show that the most economical alternative for a large range of construction and circulation cost alternatives is to convert existing ground space to…

Outlines a model for determining library collection use, incorporating prediction of future demand and cost analysis to assist collection development librarians determine whether weeding or remote storage is the most economically feasible way to address the space problem in libraries.
