Although the beginning of legislative reference service by the Library of Congress can be identified as early as 1815, a more specialized organization with the specific responsibility of providing such assistance emerged with support from leaders of the Progressive Movement just before the dawn of World War I. Subsequent revisions of this mandate in 1946 and 1970 have resulted in the current Congressional Research Service, which continues to meet the requirements of responsiveness, objectivity, and tolerance that are much a part of its two hundred years of tradition. 相似文献

This study examines the decision-making process for Hispanic families living in the United States who have a child with a hearing loss. Twenty-nine families in four geographical areas shared their experiences in searching for appropriate interventions and making choices regarding communication and education. We explored the impact of language, culture, minority status, and access to information and services on the decision-making process. The results indicate that the deliberations of Hispanic parents are often complicated by language and cultural barriers and by limited access to information, resources, and a full range of options. The communication method chosen tended to be the one recommended by professionals, usually a combination of spoken English and sign language. Parents frequently expressed the hope that their child would learn Spanish as well. These subjects displayed a higher degree of assertiveness in obtaining services for their children than other studies have suggested. 相似文献

AbstractCollection development analysis in academic libraries typically involves collection-centered and user-centered methods. These approaches focus on building collections that help students with their academic needs but may overlook resources that students need experience with when employed. To address this gap, the authors analyzed early-career advertising agency positions to identify a list of information resources that advertising agencies expect employees to use. This list was then compared against the library websites of 158 universities with advertising programs to see how sufficiently libraries are fulfilling these resource needs. The authors found that overall, university libraries only subscribe to a small number of resources used by advertising agencies. 相似文献
