The extent to which scholarly literature can be openly accessed and freely downloaded on the Internet varies greatly depending on the discipline. This article assesses the current state of open access in the fields of business and management. Google was used to search for free versions of articles from a sample of articles published in early 2009 in a broad array of business and management journals. Free versions of 36% of the articles included in this study were identified, available from a wide variety of websites, including repositories, author profile pages, open access journals, and more.  相似文献

This paper presents the results of two complementary surveys undertaken in 2008 as part of a wider project investigating the effects and impact of open access to research outputs in the UK. The institutional view, from a survey of academic librarians, is compared to researchers' perceptions and practices. Researchers were largely unaware of their institutions' policies with regard to open access, or whether they had an institutional repository. Reasons for making research outputs available on open access, or not doing so, were sought, and the role of open access material as a research resource investigated. The surveys found that many researchers maintained a suspicion of open access publications, both as authors and as users of scholarly material, together with a degree of ignorance about open access and the role of institutional repositories. This suggests that a degree of culture change may be needed, as institutions develop repositories with a view to future research assessment requirements, and more funders adopt open access mandates for the outputs from research which they fund.  相似文献

In 2005, the Scott Memorial Library at Thomas Jefferson University started an institutional repository (IR), the Jefferson Digital Commons (JDC) <http://jdc.jefferson.edu/>. Originally intended as a showcase for faculty scholarship, it has evolved to serve also as a university press for original journals and newsletters, and as an institutional archive. Many lessons have been learned about marketing techniques, common IR issues, and advantages of an IR for a library. IR recruitment has come to be viewed as yet another form of collection development and has been integrated into all forms of the Library's outreach. Jefferson's academic health sciences environment has proven similar to other academic environments on issues of acceptance and participation.  相似文献

开放存取的质量控制   总被引:1,自引:0,他引:1  
布达佩斯开放存取计划提出了实现开放存取的两种途径:一是自存档,即建立开放存取仓储:二是创办开放存取期刊。本文分别对开放存取期刊和开放存取仓储的质量控制问题作了分析和介绍。  相似文献
