The literature of medical librarianship of Nigeria is reviewed. The staff structure of Nigerian univeristy libraries and, in particular, of the medical libraries attached to them is restrictive, unprogressive, and unconducive to the development of medical librarianship in Nigeria. These medical libraries should cease to be administered and regarded as just unavoidable appendages of the main university libraries. They should be independent, full-fledged libraries of their own, recognixed as full academic departments of their respective colleges or faculties, with their heads being in no way inferior in status to other heads of academic departments.The granting of faculty status to Nigerian unviersity librarians should go the whole way and let the principle of multiple professorships be applied to the staff structure of unviersity libraries. Efforts are being made to effect bibliographic organization of Nigerian medical literature. A national library of medicine for Nigeria, however, humble its beginning, should be established. 相似文献

This paper describes the procedures used at the Library of the College of Physicians of Philadelphia to divide its ninety-year-old dictionary card catalog. The division was necessitated by overcrowding, obsolete subject headings, and lack of a complete authority list which resulted in like materials being scattered throughout the catalog under several headings. Two catalogs were created: the historical-biographical catalog, representing all works published before 1950 and all works of historical or biographical nature; and the current catalog, containing all works published from 1950 on, excepting historical or biographical materials. The 1950- catalog was further divided into name and subject catalogs, and the subject section was revised according to MeSH. The project was completed in about two years. As a result, searching time has been much reduced, and the library is able to take advantage of the annual revisions of MeSH to update the subject catalog. 相似文献

An ongoing debate regarding the nature of therapeutic communities concerns the extent to which these communities reinforce the ideologies of individualism and community. This article engages this discussion through a process of social text analysis informed by the dialogism theory of Russian philosopher and literary scholar Mikhail Bakhtin. Dialogism seeks to understand the multiple voices interpenetrating particular utterances, revealing an emergent social construction of meaning. Applying this approach to examples of discourse from a prominent therapeutic community, Alcoholics Anonymous, illustrates how meaning in the discourse of this movement can be understood to emerge among the interplay between the ideologies of individualism and community as expressed within the movement's narrative practice. 相似文献

OBJECTIVES: The objective is to highlight the important role that librarians have in teaching within a successful medical informatics program. Librarians regularly utilize skills that, although not technology dependent, are essential to conducting computer-based research. The Metropolis analogy is used to introduce the part librarians play as informatics partners. Science fiction is a modern mythology that, beyond a technical exterior, has lasting value in its ability to reflect the human condition. The teaching of medical informatics, an intersection of technology and knowledge, is also most relevant when it transcends the operation of databases and systems. Librarians can teach students to understand, research, and utilize information beyond specific technologies. METHODS: A survey of twenty-six informatics programs was conducted during 2002, with specific emphasis on the role of the library service. RESULTS: The survey demonstrated that librarians currently do have a central role in informatics instruction, and that library-focused skills form a significant part of the curriculum in many of those programs. In addition, librarians have creative opportunities to enhance their involvement in informatics training. As a sample program in the study, the development of the informatics course at the Massachusetts College of Pharmacy and Health Sciences is included. CONCLUSIONS: Medical informatics training is a wonderful opportunity for librarians to collaborate with professionals from the sciences and other information disciplines. Librarians' unique combination of human research and technology skills provides a valuable contribution to any program. 相似文献

In this essay, we respond to the narratives and essays in this issue by examining organizational power issues related to researchers and institutional research boards (IRBs). Rather than taking a singular perspective on power, we use multiple perspectives and suggest that the cumulative analyses provide the best understanding of IRBs and organizational power. 相似文献

Taking on responsibilities in research data management (RDM) has proven to be a significant challenge as libraries have adopted new roles within higher education institutions. A qualitative review using the meta-ethnographic approach was conducted that examined the experiences of academic libraries and provided clarity on contextual influences associated with achievements, as well as illuminating the reasons for deficiencies. Libraries experienced uncertainty around roles and relationships related to RDM yet were recognized positively as a neutral, centralized space within academic institutions. This perception, combined with the current approach of fostering partnerships and collaborations, may prove to be useful for libraries as they strategically consider how best to provide continued support and services in RDM. Understanding the perspectives of academic libraries on how they respond and support the demands related to RDM offers a fuller, more robust insight that is essential for planning and decision-making. 相似文献
