The DigitalHub scholarly repository was developed and launched at the Galter Health Sciences Library for the Feinberg School of Medicine and the greater Northwestern Medicine community. The repository was designed to allow scholars the ability to create, share, and preserve a range of citable digital outputs. This article traces the evolution of DigitalHub’s development and engagement activities, highlighting project challenges, innovations, success stories, and the team-based approach that was employed to successfully achieve project goals. 相似文献

The importance of a national bibliography can not be overemphasized. It may be published by any body in the country, though, usually the national library of the country is the body responsible for its publication. National deposit is necessary for its comprehensiveness. This paper deals with the state of the national bibliography in Ethiopia, its origin, establishment of the National Library of Ethiopia and law of deposit. Ethiopia is one of the three countries in Africa where lists of their publications from the 19th century are found. Two organizations were identified which were engaged in publishing the national bibliography in Ethiopia: one is the National Library and Archives of Ethiopia by the virtue of the power invested through legal deposit and another is the Institute of Ethiopian Studies, to enablc it to provide documentation services to its users. It seems uncconomical and irrational. It is recommended that all the three organizations, the National Library, the Institute of Ethiopian Studies and the National Archives of Ethiopia, should be separated to look after their own specific functions and perform their own specialized duties. 相似文献

认为国外持久标识符的研究存在研究对象过于具体、应用范围有限等不足,很大程度上是由于没有在一个整体框架指导下来开展研究所致,鉴于此,提出一个持久标识符互操作参考模型,模型主要组成部分是持久标识符域,包括登记机构、内容提供商以及解析器等,对三类数字资源实体（数字对象、作者、机构）和持久标识符之间的关系进行标准化,便于管理、表示和呈现数字资源,并可为实现正确的互操作解决方案和交换奠定基础。最后,指出本模型在安全性、可伸缩性等方面有待进一步完善和改良。 相似文献

Bibliographic records in the Innovative library catalog at Kent State University Libraries had fallen out of synchronization with the Libraries’ holdings represented on OCLC's WorldCat database. The Libraries made a decision to undertake a batch reclamation project with OCLC to re-synch their holdings on WorldCat. This project was beneficial for both parties. OCLC received a clean copy of the Libraries’ database, while the Libraries were able to improve the quality of their local bibliographic data and address problem areas in the catalog. This case study is intended to provide a reference for other libraries considering OCLC batch reclamation projects. 相似文献
