This paper presents the results from a quantitative and systematic analysis comparing the online usage of an e-reference and an e-monograph collection. A very strong relationship exists between size and usage: the larger the collection, the greater the usage. An equally strong relationship exists between searches and viewings, meaning that the…

Academic libraries are increasingly collecting e-books, but little research has investigated how students use e-books compared to print texts. This study used a prompted think-aloud method to gain an understanding of the information retrieval behavior of students in both formats. Qualitative analysis identified themes that will inform instruction…

Compares the impact of manual and online search methods on the interdisciplinary search task in terms of relevance of retrieved items, user effort, user satisfaction, user confidence, and future use. The study, using the Kuhlthau model, focused on journalism classes researching judicial decisions relating to mass media. (31 references) (Author/KRN)

This two-part study was designed (1) to determine differences in the costs of searching BRS After Dark (BRS AD) and Knowledge Index (KI) generally and across ten selected databases, and (2) to determine whether there is a difference in the citations retrieved when the same search is conducted on the same database in both systems. Study methodology…

To assist librarians to better understand the information needs of industrial vs academic patrons, this study considers the purpose of searches, the sources checked prior to requesting searches, search characteristics, users' opinion of search results, and typical search profiles of the two groups.

The relative effectiveness of the CD-ROM information retrieval system, InfoTrac II, and the manual "Readers' Guide to Periodical Literature," was studied. Seventeen community college students were divided into two groups which researched the same questions either on CD-ROM or in the printed index. Results showed the "Readers'…

The purpose of this study was to improve upon previous research investigations by analyzing the elements of cost effectiveness, precision, recall, citation overlap, and hours searching in a comparison between computerized database searching and manual searching, using the setting of an academic library environment with a diverse group of students…

The first phase of a project to design a prompting system to help semi-experienced end users to search Chemical Abstracts online, this study focused on the differences and similarities in the search approaches used by experienced users and those with less expertise. Four online searches on topics solicited from chemistry professors in small…

This report by the BRS (Bibliographic Retrieval Services) Committee, which was formed to identify costs and benefits of joining BRS, provides a summary of anticipated use of the BRS system and projected savings, and recommendations to the library on joining BRS. The majority of the report comprises seven appendices: (1) a comparison of search…

Describes government information available in machine-readable data files--primarily on computer tapes--in relation to other formats and examines requirements for their acquisition, preservation, and utilization in retrieval and reference services. Skill and knowledge adjustments on the part of librarians are also discussed, and a system in use at…

A survey of 123 users at the National Agricultural Library and Purdue University showed that, for most measures of acceptability, users preferred online or digital videodisc versions of the Pork Industry Handbook to the printed version. User characteristics were examined as factors that might influence responses. (Author/MES)

Describes a project that demonstrates subject searching in an experimental online catalog based on academic library databases that were enhanced with search trees; compares the retrieval effectiveness of search trees with random subject searching approaches; evaluates system and retrieval effectiveness; and discusses proposed research. (Contains…

Describes a project intended to improve subject access in an online catalog by adding multiword terms from the table of contents and index to MARC records for each book. The discussion covers a preliminary evaluation of the impact on workload, resources, and subject access to information. (seven references) (Author/CLB)

This study reports and compares patron usage rates from January 1987 to May 1988 for three separate ERIC database systems at the library at Texas Woman's University (TWU): (1) online searches of the ERIC file through the mainframe computers of DIALOG Information Services (DIALOG ERIC), which are offered in the library reference department by…

Results of study on patron information retrieval success and patron use patterns at Ohio State University show that 90 percent of online users preferred online to card catalog; 64 percent of those who tried online catalog switched to it; and patrons used the online more than the card catalog.
