For this talk, Marks was tasked with summarizing the important trends in scholarly publishing in 45 minutes. The speaker reflected on the rapid changes that have occurred in journal publishing, which followed more than 300 years of relatively slow progress. Marks discussed key technology trends such as data curation, Open Access (OA) mandates, and the changes occurring in the global landscape of scholarly communications and library budgets. Wolters Kluwer Health has been responding to these trends with new publishing experiments including a Platinum OA model in emerging markets. Marks discussed the ways that publishers and libraries need to alter their traditional practices and instill a focus on their customers and communities.  相似文献

This session reported the findings of a comparative analysis of how e-books are represented across multiple platforms. In this session, the presenters shared the results of a study that examined how a sample of academic e-books are represented across different platforms. Topics of analysis included: the inclusion of various metadata, the visual presentation of e-book content, and variations in search results. This presentation also focused on the similarities and differences between e-book representation and what impact these various representations might have on users of academic e-books.  相似文献

On the surface, it might appear that libraries with different collections, staffing levels, and budgets would have to make use of different tools to address their e-resource management needs. However, in their review of electronic resources lifecycle work at North Carolina State University and Georgia Perimeter College, Tessa Minchew and Sofia Slutskaya discovered that this is not always the case. The presenters reviewed the electronic resources lifecycle and three distinct types of tools (content management systems/wikis, Microsoft Access, and Trello) that are being used in different ways to address different lifecycle-related tasks at each of their institutions.  相似文献

The University of North Texas Libraries provide extensive online access to academic journals through major vendor databases. As illustrated by interlibrary loan borrowing requests for items held in our databases, patrons often have difficulty navigating the available resources. In this study, the Interlibrary Loan staff used data gathered from the ILLiad interlibrary loan management system to investigate why patrons request locally available materials. This study resulted in recommendations for the Libraries' linking strategies in EBSCOhost databases. Several user education needs were identified and communicated to the Libraries' Subject Liaisons.  相似文献

A long term action research programme initiated in 1987 by the Department of Communication Studies at the Victoria University of Wellington, New Zealand, is seeking to develop a virtual class. The virtual class is regarded as the critical component of a new educational paradigm for an information society. The action research programme takes the form of a spiral of cyclical attempts to create a virtual class. Each attempt is seen as a syntagmatic episode of a virtual class paradigm attempted in the light of an existing paradigm. The results of each syntagmatic episode are seen as influencing the further development of the paradigm.  相似文献
