The researcher identified 37 independent variables to study their effect on the two dependent variables, the acquisition of videodiscs and the functions for which videodisc programs were acquired. The literature of the applications of videodisc technology in libraries, museums, education and industry, as well as related issues concerning interactive video, were presented in Chapter 2. Using the diffusion of innovation theory of Everett Rogers as a guide, the researcher constructed a questionnaire. Valid responses totaled 462 from management of all types of academic libraries and from special libraries other than non-academic law, military, veterans' hospital, and church libraries. The following conclusions were made from the results: there were significant correlations between having videodiscs and perceptions of greater benefits than costs, appropriateness of videodisc programs for libraries' objectives or curricula, seeing videodiscs as an enhancement of an existing library technology, collection of videocassettes, and ability to raise funds from slack resources. The size of the libraries' materials and equipment budgets had some significance, but it was not consistently significant, as it was for the above-mentioned factors, at the p < .01 level. Lack of in-house recording ability did not impose a barrier on adoption of discs among respondents. Full--motion, full-screen video …

Wayfinding is the process of using one or more tools to move from one location to another in order to accomplish a task or to achieve a goal. This qualitative study explores the process of wayfinding as it applies to locating information in a public library. A group of volunteers were asked to find a selection of items in three types of libraries-traditional, contemporary, and modern. The retrieval process was timed and the reactions of the volunteers were recorded, documented, and analyzed. The impact of various wayfinding tools-architecture, layout, color, signage, computer support, collection organization-on the retrieval process was also identified. The study revealed that many of the wayfinding tools currently available in libraries do not facilitate item retrieval. Inconsistencies, ambiguities, obstructions, disparities, and operational deficiencies all contributed to end-user frustration and retrieval failure. The study suggests that failing to address these issues may prompt library patrons-end users who are increasingly interested in finding information with minimal expenditures of time and effort-may turn to other information-retrieval strategies and abandon a system that they find confusing and frustrating.

This is the first known study to explore the image retrieval preferences of news photographers and news photo editors in work contexts. Survey participants (n=102) provided opinions regarding 11 photograph searching methods. The quantitative survey data were analyzed using descriptive statistics, while content analysis was used to evaluate the qualitative survey data. In addition, news photographers and news photo editors (n=11) participated in interviews. Data from the interviews were analyzed with phenomenography. The survey data demonstrated that most participants prefer searching by events taking place in the photograph, objects that exist in the photograph, photographer-provided keywords, and relevant metadata, such as the date the picture was taken. They also prefer browsing. Respondents had mixed opinions about searching by emotions elicited in a photograph, as well as the environmental conditions represented in a photograph. Participants' lowest-rated methods included color and light, lines and shapes, and depth, shadow, or perspective. They also expressed little interest in technical information about a photograph, such as shutter speed and aperture. Interview participants' opinions about the search methods reflected the survey respondents' views. They discussed other aspects of news photography as well, including the stories told by the pictures, technical concerns about digital photography, and digital …
