This paper addresses the need to recognize the importance, and the challenges, of preserving the hugely expanding record of medicine today for historians of the future. We are faced not only with an increase in traditional publishing formats, but also with the rapid growth in electronic communications. Two celebrated medical cases, one from the late seventeenth century and one from the late twentieth, are used to illustrate the differences and the difficulties. The need for active and effective professional collaboration is stressed; libraries should work together to address these issues. 相似文献

As a part of efforts to evaluate and monitor the increasing public investment in early childhood education, teachers are being asked to assess children's school readiness. In this study, preschool teachers and kindergarten teachers rated children's skills in three areas (kindergarten readiness, academic skills, and communication skills), and these ratings were compared with direct assessments of the children's skills. Ratings by both groups of teachers tended to be more highly related to basic skills, such as counting and number naming, than to abilities such as solving applied problems and using expressive and receptive vocabulary. Preschool teachers' ratings had a lower association with children's observed skills and abilities than kindergarten teachers' ratings. Ratings of children attending Head Start were systematically inflated, but this relationship was mediated to a significant extent by the teachers' levels of education. More educated teachers rated children in a manner consistent with the children's directly assessed skills. Implications of these findings for informing future efforts to assess school readiness by using teacher ratings are discussed. 相似文献

The authors report on a self‐completed questionnaire study from a North Yorkshire based general practice regarding the information needs of its clinicians. The work was carried out with a particular focus on the practice library, and the findings identified that a new approach to maintaining and developing the library was needed. The literature regarding the information needs of primary care clinicians and the role of practice libraries is considered, and compared to those of the clinicians at the practice. Discussion follows on how a collaborative project was set up between the practice and a librarian based at the local NHS Trust library in order to improve the existing practice library. Difficulties encountered and issues unique to the project are explored, including training implications presented by the implementation of electronic resources. Marketing activities implemented are discussed, how the library will operate in its new capacity, and how ongoing support and maintenance of the library will be carried out. It is concluded that although scepticism still exists regarding librarian involvement in practice libraries, collaboration between clinicians and librarians is an effective approach to the successful development and maintenance of a practice library, and recommendations are therefore made for similar collaborative work. 相似文献
