Comprehensive yet efficient search methods are essential for any systematic or scoping review. This article outlines the stages of development of a systematic search methodology for a scoping review within the library and information science (LIS) literature. The effectiveness of the database search strategies (LISTA, LISA, ERIC, Scopus, Web of Science) and supplemental search techniques are measured through a retrospective analysis of performance metrics. Findings show that for research topics limited to the library setting, it may be more effective to search fewer databases (LISTA and Scopus only) for peer reviewed journal articles and allot more time to alternate search techniques such as web searching to identify non-journal literature. The article provides an evidence-based, methodological approach to developing a systematic search plan, unique to LIS researchers, that accounts for time and resource needs.  相似文献

The "Online Updates" column generally focuses on bibliographic databases that may be licensed from commercial vendors or are available free of charge from a federal government agency. HazLit is featured because it is a unique and comprehensive resource of the literature of natural disasters. This column provides background information on HazLit and offers some searching basics, as well as highlights special information found at the Web site that hosts the database.  相似文献

The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. For the search of nursing care literature on a medical condition, it was helpful to search both CINAHL and MEDLINE. CINAHL provided the majority of relevant articles for the second search, on computers and privacy, but inclusion of MEDLINE and EMBASE enhanced retrieval somewhat. The search on substance abuse in pregnancy, not restricted to nursing literature, retrieved better results when searching both MEDLINE and EMBASE. Due to the nature and distribution of the nursing literature, it is especially important for the searcher to understand and respond to the focus of the researcher.  相似文献

The current national education crisis makes it imperative for educators to identify relevant research and development on new and innovative instructional techniques. The United States Department of Defense (DOD) has significant education and training responsibilities that could be useful in providing instructional technology for transfer to civilian applications. However, we propose that there is a gap between the holdings of ERIC, the primary education database, and NTIS, the main database for information on the activities of Federal government agencies, including the DOD. Much information with a Federal derivation may not be cited in ERIC. We develop a series of search statements based on these propositions. These are applied to each database and the results analyzed. Findings substantiate at least a limited gap that must be recognized by educators and information professionals and that has implications for testing holdings of other databases.  相似文献

The present scoping review examines empirical RDM instruction-related studies in academic libraries between 2010 and 2021. We searched three databases (LISTA, ERIC, and MEDLINE Complete) and two journals (Journal of eScience Librarianship and International Journal of Digital Curation) and identified 124 articles for inclusion. Cohen's kappa indicated a strong to perfect inter-rater reliability on the coding between the authors. Overall, the findings indicate an increasing trend in empirical research regarding the topic of RDM instruction across many countries and regions after 2010. Also, faculty, researchers, and librarians in the higher education field were the primary audiences for the RDM instruction with few studies addressing RDM instruction for the undergraduate and graduate levels. In terms of the RDM aspects, RDM needs assessments were investigated the most among the reviewed studies, followed by data sharing and data management plans. Additionally, the face-to-face learning context was the most popular for RDM instruction, followed by online and hybrid contexts. However, few studies used an intervention research design while delivering instruction to the target audience. This study highlights the substantial characteristics and methodological designs of the RDM instruction empirical research and provides implications for approaches and techniques used to study RDM instruction in academic libraries.  相似文献

OBJECTIVE: The research sought to examine the overlap in coverage between several health-related databases, thus enabling the identification of the most important sources for searching for information on the rehabilitation of people with severe mental illness. METHODS: The literature was searched within a systematic review. Several health-related databases were retrieved (Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library, MEDLINE, PsycLIT, Sociofile, and Social Science Citation Index), noting their source and comparing results retrieved from each database. FINDINGS: The total number of studies retrieved from each database varied. Almost a third of the papers retrieved from each database were unique to that source. Forty-two percent of the papers were only found in one database. Restricting a search to one database alone would miss many papers and could affect the results of a systematic review. PsycLIT was the most useful database for this topic area, containing 44% of the papers. MEDLINE, the database of first choice for many health professionals, held only 29%. CONCLUSIONS: No database was determined to be significantly more useful than any other--each warranted inclusion in the study. Reliance cannot be placed on one database alone, and other methods such as hand searching should also be used. Although this may not be new information for information professionals, it is likely to be new for health professionals and researchers who are increasingly performing their own literature searches. Information professionals have an important role to play in conveying this message to those outside their profession.  相似文献

This paper describes a national experiment in the licensing of full text information in journals, primarily in the fields of science, technology and medicine. It discusses the initiative of the federal government of Canada through the creation of the Canada Foundation for Innovation as a new funding agency, with an objective of improving research and creativity in Canadian science. The successful efforts initiated by the Canadian Association of Research Libraries/Association des bibliothèques de recherche du Canada to create a funding opportunity to develop the ‘information infrastructure’ for Canadian researchers and the resulting Canadian National Site Licensing Project (CNSLP) progress is discussed. The evolution of a project governance structure to maintain the support of the 64 participating institutions is reviewed and the need to develop an appropriate exit strategy at the conclusion of the federal funding is also considered.  相似文献

This study was designed to make a comparative evaluation of the performance of MEDLINE in covering serial literature. Forensic medicine was chosen because it is an interdisciplinary subject area that would test MEDLARS at the periphery of the system. The evaluation of database coverage was based upon articles included in the bibliographies of scholars in the field of forensic medicine. This method was considered appropriate for characterizing work used by researchers in this field. The results of comparing MEDLINE to other databases evoked some concerns about the selective indexing policy of MEDLINE in serving the interests of those working in forensic medicine.  相似文献

Summary

The objective of this article is to examine some of the valuable philosophical resources available on the Internet, especially for librarians who need to determine what resources to provide to faculty, students, and staff. Some main uses of the Internet for philosophical research are: accessing texts, using search strategies to examine the texts, reading and writing electronic journal articles, accessing information from encyclopedias and dictionaries, browsing through paths of interlinked Web sites, searching the Internet for sources, and participating in online discussion forums. This article examines the Internet as a source of primary and secondary texts, journal literature, research databases, reference works, specialized limited area search engines, organizational information, and discussion lists. The article ends with a philosophical reflection on the transformative effect of information technology on the growth of knowledge.  相似文献

The legal support for information security is found in two conditionally independent areas: the macro area, which is external in relation to organizational factors, and the micro area, which includes internal legal factors. In this paper the federal legislation is examined and the fundamental and private principles of construction of a legal basis of information in Russia are noted. It is underlined that the legal macro support of an organization is incomplete and does not protect the interests of the private owner of information. The author reviews micro support and the approximate structure and content of internal legal regulations of an organization are proposed as well. The principles of organizational support for the protection of information are made. The role of the human factor in the support of security of information is justified.  相似文献

A National Library of Medicine information access grant allowed for a collaborative project to provide computer resources in fourteen clinical practice sites that enabled health care professionals to access medical information via PubMed and the Internet. Health care professionals were taught how to access quality, cost-effective information that was user friendly and would result in improved patient care. Selected sites were located in medically underserved areas and received a computer, a printer, and, during year one, a fax machine. Participants were provided dial-up Internet service or were connected to the affiliated hospital's network. Clinicians were trained in how to search PubMed as a tool for practicing evidence-based medicine and to support clinical decision making. Health care providers were also taught how to find patient-education materials and continuing education programs and how to network with other professionals. Prior to the training, participants completed a questionnaire to assess their computer skills and familiarity with searching the Internet, MEDLINE, and other health-related databases. Responses indicated favorable changes in information-seeking behavior, including an increased frequency in conducting MEDLINE searches and Internet searches for work-related information.  相似文献

QUESTION: How have theorists and empirical researchers treated the human tendency to avoid discomforting information? DATA SOURCES: A historical review (1890-2004) of theory literature in communication and information studies, coupled with searches of recent studies on uptake of genetic testing and on coping strategies of cancer patients, was performed. STUDY SELECTION: The authors' review of the recent literature included searches of the MEDLINE, PsychInfo, and CINAHL databases between 1992 and summer of 2004 and selective, manual searches of earlier literature. Search strategies included the following subject headings and key words: MeSH headings: Genetic Screening/psychology, Decision Making, Neoplasms/diagnosis/genetics/psychology; CINAHL headings: Genetic Screening, Genetic Counseling, Anxiety, Decision Making, Decision Making/Patient; additional key words: avoidance, worry, monitoring, blunting, cancer. The "Related Articles" function in MEDLINE was used to perform additional "citation pearl" searching. MAIN RESULTS: The assumption that individuals actively seek information underlies much of psychological theory and communication practice, as well as most models of the information-seeking process. However, much research has also noted that sometimes people avoid information, if paying attention to it will cause mental discomfort or dissonance. Cancer information in general and genetic screening for cancer in particular are discussed as examples to illustrate this pattern. CONCLUSION: That some patients avoid knowledge of imminent disease makes avoidance behavior an important area for social and psychological research, particularly with regard to genetic testing.  相似文献

Journal coverage is one factor that affects the retrieval of relevant information from bibliographic databases. The aims of this study were to investigate the coverage of databases for psychiatry journals, and to assess the overlap between databases. Psychiatry journals were identified using Ulrich’s International Periodicals Directory and then analysed to see which bibliographic databases indexed the most journals. A total of 213 abstracting and indexing services were listed as indexing at least one of the 977 psychiatry journals identified. The four most frequently cited databases (PsycLIT, EMBASE, BIOSIS and MEDLINE) indexed 506 (52%) of the psychiatry journals. Of these 506 journals, PsycLIT indexed 367 (73%), EMBASE 337 (67%), BIOSIS 243 (48%) and MEDLINE 236 (47%). Combining the databases with the highest yields (PsycLIT and EMBASE) increased the number of journals indexed to 461 (91%). The four databases combined accounted for 90% of all psychiatry journals found to be indexed by at least one abstracting and indexing service. More than 400 journals were not indexed at all. Variations in the overlap between PsycLIT, EMBASE, BIOSIS and MEDLINE, and the high proportion (35%) of journals indexed in only one of these four databases emphasize the importance of searching more than one or even two databases to ensure optimal coverage of the literature.  相似文献

An exploratory study to investigate perceived differences between searching full-text databases and bibliographic databases was undertaken. BRS's full-text database, Comprehensive Core Medical Library (CCML), and BRS's current MEDLINE file (MESH) were compared. Identical literature search topics were run in the two databases and the results evaluated regarding currency of search results, success in answering specific questions, uniqueness of information retrieved, and relevancy of retrieval. Additionally, connect time and costs were noted to aid in determining the feasibility of offering full-text database searching as a service for which the authors' institution would charge.  相似文献
