Understanding user needs need not be based on guesswork, yet there may be shortcut data collection alternatives to traditional expensive and timeconsuming library user surveys. Depository libraries are required to select useful materials to provide government information meeting the needs of area users. Assessing user needs is vital to library planning and to the development of library collection and public services policies. In any planning or assessment process, it is critical to define the specific planning purpose before determining the data to be collected and the methods of collection. There are various qualitative techniques for obtaining user information. Community surveys, published documents, library internal reports, and databases also yield user information. Alternatives to traditional user surveys provide the increased utility of improving communication among area information users and providers. A group process, which allows participants to hear each other, may be more effective and efficient than a written survey. The Nominal Group Technique (NGT), creates a listening forum, providing library administrators with information for planning. 相似文献

Information behavior research has been conducted predominantly using single-method (often interviews or surveys/questionnaires), cross-sectional research designs. However, there are important benefits to triangulation and the use of longitudinal methods. In preparing to conduct an investigation into the information needs and information seeking and use practices of people with type 2 diabetes, a longitudinal research design was developed that included traditional data collection methods, such as questionnaires and interviews. However, an additional method was developed specifically for this study — a new type of card-sorting technique that would permit the elicitation of participants' judgments regarding the relative usefulness of different sources and types of diabetes related information at different points in time along their journeys with the disease. This technique was well-received by the study participants and it yielded quantitative data that could be analyzed to identify whether any statistically significant changes took place in participants' judgments across time. Furthermore, the incorporation of a think-aloud protocol within this technique yielded invaluable qualitative data that helped to shed light on the reasoning behind participants' usefulness judgments. This new data collection tool has many potential applications within LIS research and practice. 相似文献

Collection development in college and university libraries most often occurs using longstanding traditional selection methods, such as favorable book reviews or local user needs. This study uses citation analysis as a tool to select books for the social science book collection in one academic library and compares the circulation of books using traditional methods to those books using citation analysis. The journal impact factor was used to determine those journals and authors cited the most in the disciplines of business, anthropology, education, political science, psychology, and sociology. If those authors published books, the books were purchased and circulation data on the books were tabulated and compared to books chosen using traditional methods. Findings indicate that books purchased using traditional methods of selection circulated more, except when individual disciplines were measured. In the areas of business, political science, and psychology, there was no significant difference in circulation statistics, and together both the traditional and citation analysis methods accounted for circulation of nearly 95% of the social science collection. Since it is based on scholarly activity, citation analysis is a collection development method that could be used in all academic libraries. 相似文献

Research methods are applied in all kinds of studies, though no consensus exists regarding what constitutes a research method and how research methods should be categorized. Over 1900 research articles were obtained from three major journals published between 2001 and 2010 in library and information science (LIS). Each selected article was coded using a schema of research methods developed in this study. The coded data, along with related publications, were analyzed qualitatively and quantitatively. This exploration shows that research methods comprise data collection techniques (e.g., interview, observation) and data analysis techniques (e.g., qualitative, quantitative). Research methods should perhaps be categorized by data collection technique, as it makes more sense than if research methods are labeled as qualitative or quantitative. This study is one of the many efforts to facilitate a better understanding of research methods in LIS and help scholars make more informed decisions about research method selection in their endeavors. Its implications can be extended to LIS research education, training, and advocacy. Because research methods themselves are not discipline-specific, researchers beyond the LIS field would benefit from this study as well. 相似文献

Many areas of the country have seen large growth in their Spanish speaking community. Libraries and other public agencies have redesigned their practices to better serve the needs of these new segments of the population. The urban area chosen for this study has experienced one of the fastest growing Spanish speaking populations in the country in the last 10 years. In this study, a needs assessment was created for the Spanish speaking population served by a branch library in a large, urban area. The needs assessment was created with the use of demographic data and an analysis of current library literature. Using the assessment, the current Spanish nonfiction collection of the library was evaluated for both size and content and then compared to the size and content of the English nonfiction collection. This assessment technique is useful to libraries wishing to conduct a needs analysis on a specific group in their population served. 相似文献

This study aim to gain insight into the information-seeking habits of upper-division business students. While studying information-seeking habits is a large subcategory of information literacy, not much has been published on the information-seeking habits of business students. The majority of studies conducted in this area use the survey as the data-collection instrument. This study uses ethnographic research methods such as journaling to collect data on this unique user group. Ethnographic methods allow the researcher to capture rich qualitative information that will yield a deeper and more nuanced understanding of the user group's needs. Findings are examined by using thematic qualitative analysis techniques. Information gathered for this study will be used to develop new services and information literacy components for business students. 相似文献

To evaluate Information Retrieval Systems on their effectiveness, evaluation programs such as TREC offer a rigorous methodology
as well as benchmark collections. Whatever the evaluation collection used, effectiveness is generally considered globally,
averaging the results over a set of information needs. As a result, the variability of system performance is hidden as the
similarities and differences from one system to another are averaged. Moreover, the topics on which a given system succeeds
or fails are left unknown. In this paper we propose an approach based on data analysis methods (correspondence analysis and
clustering) to discover correlations between systems and to find trends in topic/system correlations. We show that it is possible
to cluster topics and systems according to system performance on these topics, some system clusters being better on some topics.
Finally, we propose a new method to consider complementary systems as based on their performances which can be applied for
example in the case of repeated queries. We consider the system profile based on the similarity of the set of TREC topics
on which systems achieve similar levels of performance. We show that this method is effective when using the TREC ad hoc collection. 相似文献
