Abstract It is only a few short years since the early academic research led by Herbert Van de Sompel at Ghent University in Belgium that resulted in the formulation of the OpenURL standard and the development of the SFX link server. These complementary components have revolutionized linking for libraries, putting control for linking in the hands of the librarian. This paper considers briefly the early linking initiatives, explains the purpose and structure of the OpenURL and the role of linking components-the sources, targets, and the link server, with a focus on the SFX link server. 相似文献

Ever since OpenURL linking was introduced in 2000 by Herbert van de Sompel the link resolver has played an important role in providing users with access to the online resources they have rights to. From the start, one of the criticisms of OpenURL linking has been that it is not 100% successful—sometimes the user is presented with a link to full text, but that link fails. In 2010 a new National Information Standards Organization (NISO) workgroup was created to tackle the issue of OpenURL quality. This column will discuss this NISO initiative and look in detail at the proposed “Completeness Index” that promises a means of measuring the quality of OpenURLs being submitted by various content providers. The article will also discuss how some OpenURL quality issues may be more perception than reality and how librarians can configure their links and link resolvers to overcome these negative perceptions. 相似文献

Abstract Popular for their ability to provide full-text linking, OpenURL link servers, such as SFX, can also interface with online catalogs and interlibrary loan modules, giving library users the ability to locate articles in print or request items not owned by their local institution. This article examines four different approaches to integrating print holding information into SFX, detailing the advantages and drawbacks of each approach. The ultimate goal is to provide end-users with comprehensive, dynamic access to the full range of core library services, including online full-text, print materials, and interlibrary loan. 相似文献

Summary The emergence of federated search tools for the library market represents a significant step toward the longstanding goal of a common searching interface in the reference environment. These systems aim to provide integrated access to library resources of all types. This article describes and evaluates federated search tools from four vendors. It suggests criteria that may be useful for libraries attempting to compare and contrast this type of access tool. 相似文献
