"Change" is a critical dimension of contemporary experience. Library associations are not exempt, and they change in ways similar to other organizations. According to some authorities, four phases typify the process: diagnosis, design, implementation, and incorporation. Focusing on changes in the Medical Library Association's longstanding program of continuing education, the authors utilize the "phase framework" to chart that association's movement from a management system depending primarily upon volunteers to one in which professional staff figure prominently. The historical review serves a heuristic purpose for individuals and institutions in identifying characteristic features of the change process. 相似文献

This study, an historical survey of medical journals in Louisiana before the outbreak of the Civil War in 1861, revealed that nine journals made an appearance during the period covered-all of them published in New Orleans. Of these, two were French language journals published by a French medical society. The others were all published by individuals rather than by professional societies. Medical practices, interests, and problems of the times were clearly reflected on the pages of the journals. It is evident that medical journalism reached a high plane in the era before the Civil War. Of the nine periodicals, only one emerged as a permanent publication after the War. 相似文献

The history of nursing education in America is briefly told, with the growth of education in institutions of higher learning emphasized. Two trends in nursing education are paralleled by similar developments in nursing literature. The growth of scholarship in nursing is also noted. It is pointed out that nursing is a discipline in its own right, and that training for leadership is required. Continuing education programs are mentioned, together with the increase in nursing literature. Integrated libraries for the health sciences are recommended. 相似文献
