The many challenges faced by health sciences libraries of all types and sizes often require innovative solutions. When an innovative solution involves calculated risk taking, the approach is called intrapreneurial. At the University of Miami School of Medicine, an intrapreneurial approach solved the fiscal problems of the biomedical communications unit. The Louis Calder Memorial Library inherited these problems when the Department of the Library and Biomedical Communications was created in the early 1980s. In this paper, two intrapreneurial programs are described, and the benefit and suitability of this management style to information services are demonstrated. 相似文献

Donato Tamblé 《Archival Science》2001,1(1):83-100
Archival theory in Italy has a long tradition, going back as far as the second half of the nineteenth century, and with roots
in the 17th and 18th centuries. Central theme in the theory is themetodo storico, the principle of provenance, for the first time expressed in the late 19th century by Bonaini and Bongi. In the following
decades archivists like Casanova and Cencetti were among the leading authors. Elio Lodolini assigned himself the task to synthesize
ideas and notions, within a clear distinctions between records (registratura) and archives. One of the overall characteristics
of the rich Italian literature is the stressing of the cultural value of archives.
I have twice treated before the theme of archival theory in Italy from the fifties up to the nineties. The first time on the
occasion of the 25th anniversary of theScuola speciale per Archivisti e Bibliotecari dell'Università degli Studi “La Sapienza” di Roma in 1989, when there was an international round table on archival science in the State Archives of Rome. My essay,Italian archival science today, has been published in the proceedings of the meeting (cfr. Donato Tamblé,L'archivistica in Italia oggi, inStudi sull'archivistica, by Roma: Elio Lodolini, 1992). Some years later, in 1993, I published a book on contemporary Italian archival theory (Donato
Tamblé,La teoria archivistica italiana contemporanea (1950–1990). Profilo storico-critico (Roma, 1993) which was the sequel to the volume of Elio Lodolini on Italian archival history — (Lineamenti di storia dell'archivistica italiana (Roma, 1991). The purpose of my book was that of locating and identifying the scientific object of archival science as it
developed and was clarified in the thinking and in the lucubration of the contemporary Italian Archivists. 相似文献

V H Holtz 《Journal of the Medical Library Association》1986,74(4):305-314
Questions concerning some of the values we hold as librarians and the goals, standards, and other evaluation tools we derive from them are discussed in the context of the history of our profession and the present period of rapid change. The concepts of stable and changing paradigms and of "scientific communities" provide the foundation for consideration of how a changing conceptual framework can affect values and their application in the evaluation process. One of many possible scenarios for the future is briefly outlined to demonstrate how some traditional values may fare. 相似文献

Since a sizeable hospital must have a library, it must have a library committee. Like all hospital committees, this one is to help maintain standards of medical care and to mediate between staff and administration. Unlike others, it clusters around one elected member (the chairman) and one employee (the librarian). A dynamic librarian can, and should, influence and inspire the committee's deliberations; and must be able to depend upon the support of the physician members of the committee. 相似文献
