G S Belleh 《Bulletin of the Medical Library Association》1975,63(2):199-208
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

Antonio G. Valdecasas Virginia Correia Ana M. Correas 《Museum Management and Curatorship》2006,21(1):32-43
The first natural history collections opened to the public were inspired by a sense of curiosity and wonder about the products of nature. They were ‘cabinets of curiosities’ that offered a first-hand interaction between owner and visitors. Nowadays, these two facets of the museum experience—dialogue and wonder—have been lost, in part, due to the information overload coming via the media and the impersonal nature of the museum visit. This paper offers some reflections on the evolution of the museum visit, suggests some ways to rediscover this ‘sense of wonder’ and provides ideas on how to promote two-way communication with museum visitors. Two examples of exhibitions are offered as illustrations of the points discussed. 相似文献
