Land of Linking

ABSTRACT

The electronic linking of scholarly materials has increasingly become both confusing and exciting. An understanding of the basics of linking technologies such as the OpenURL and the Digital Object Identifier (DOI) allows librarians to better serve their constituencies. Vendors also continue to offer linking alternatives to those libraries unable to purchase link resolvers, and a knowledge of these alternatives permits librarians to make informed decisions about a comprehensive and integrated linking plan for their libraries' electronic resources.     

Improving OpenURL Linking

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.

NISO's IOTA Initiative: Measuring the Quality of OpenURL Links

The Improving OpenURLs Through Analytics (IOTA) initiative was formed by the National Information Standards Organization (NISO) in 2010 to continue a Mellon-funded project on OpenURL quality begun at Cornell University. IOTA's objective is to develop a scoring system for measuring the quality of OpenURL links generated by content providers at the citation level. OpenURLs have a history of failing to resolve correctly, but no method has been devised to benchmark them even a decade after the introduction of the underlying standard. The proposed system would generate scores based on specific evaluation metrics and thus rate providers' OpenURL quality. The system's analytical approach would also enable OpenURL providers to pinpoint linking problems and thus optimize OpenURL improvements. A public OpenURL analysis tool, which relies on link data contributed by OpenURL providers and libraries, is currently in use. Recently, IOTA approached the Knowledge Bases And Related Tools (KBART) initiative about a possible collaboration on a related project, which would investigate OpenURL linking not at the citation level, but the full-text level.     

The KBART’s Potential beyond OpenURL Linking

Knowledge Base and Related Tools (KBART), initially founded with a focus on improving OpenURL linking through the definition of best practices for exchanging title-level metadata, continues to gain traction and has the potential to be an initiative that improves not only link resolver quality but also improves discovery services, electronic resource management (ERM) systems, and even Counting Online Usage of Networked Electronic Resources (COUNTER) usage reports. In this column we quickly review the history of KBART from its inception in 2007 through the creation of the Phase 1 and Phase 2 best practices. Then we investigate how KBART can positively influence the quality of discovery services, ERM systems, and COUNTER. Finally, we put forward some suggestions on how KBART can become the key to standardizing the exchange of holdings data within the information supply chain to address needs beyond link resolvers and eliminate some redundant holdings maintenance tasks in libraries.     

OpenURL and SFX Linking

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.     

The Knowledgebase at the Center of the Universe

ABSTRACT

Since its advent more than 15 years ago, the knowledgebase has quietly deposed the catalog as the center of the library management and discovery universe. Knowledgebases provide libraries with an inventory of their e-resources holdings and describe the materials that a library has purchased at a more granular level than the traditional bibliographic record. Knowledgebases power key tools such as link resolvers and unified search platforms, support management needs across the e-resources lifecycle, and more recently have evolved to intersect with areas such as linked open data, community contribution models, and next-generation library management platforms. They have truly become the hub from which our most vital services operate. This report will provide an overview of “The Knowledgebase at the Center of the Universe,” an American Library Association Technology Report assessing the state of knowledgebase technology. Topics covered will include an overview of the current product landscape, an exploration of new directions, and case studies from libraries and vendors using knowledgebases in innovative ways.     

An availability study of electronic articles in an academic health sciences library

Objectives:

The purposes of this study were: to determine the number of articles requested by library users that could be retrieved from the library''s collection using the library catalog and link resolver, in other words, the availability rate; and to identify the nature and frequency of problems encountered in this process, so that the problems could be addressed and access to full-text articles could be improved.

Methods:

A sample of 414 requested articles was identified via link resolver log files. Library staff attempted to retrieve these articles using the library catalog and link resolver and documented access problems.

Results:

Staff were able to retrieve electronic full text for 310 articles using the catalog. An additional 21 articles were available in print, for an overall availability rate of nearly 80%. Only 68% (280) of articles could be retrieved electronically via the link resolver. The biggest barriers to access in both instances were lack of holdings and incomplete coverage. The most common problem encountered when retrieving articles via the link resolver was incomplete or inaccurate metadata.

Conclusion:

An availability study is a useful tool for measuring the quality of electronic access provided by a library and identifying and quantifying barriers to access.

Highlights

• Lack of holdings, including access to recent articles restricted by embargoes, was the most common barrier to locating full text, accounting for over 90% of all identified problems.
• Availability rates for electronic articles varied by year of publication and by the database in which the OpenURL request originated.
• Link resolver error rates varied widely based on the source of the request and frequently resulted from incomplete or inaccurate metadata.

Implications

• An availability study is an inexpensive, practical tool for assessing the quality of electronic access to journal articles.
• The results of an availability study can help libraries identify barriers to access and thereby allocate limited resources to areas that will provide the most benefit to users.
• Link resolvers might be more accurate if the quality of metadata in OpenURLs was improved and the behavior of full-text targets was standardized.

A user who attempts to access an electronic article expects the process to be seamless: click a link or two, and the article appears. Unfortunately, this process is not always so simple. Many factors can prevent users from retrieving an article, including:

• Collection and acquisition problems: The library may not subscribe to the desired journal, or the article and/or journal may be unavailable for some other reason.
• Cataloging and holdings problems: The journal may be cataloged or indexed incorrectly, or the library''s holdings data may be wrong.
• Technical problems: Problems may occur with the journal provider''s site or the library''s proxy server.

While many libraries use link resolvers to make it easier for users to retrieve articles, these can introduce additional points of failure. The resolver might not be configured correctly, the knowledgebase (database of library journal holdings) might include incorrect information, or article metadata from the source database might be incomplete or incorrect.At the Oregon Health & Science University (OHSU) Library, users occasionally complained about access problems. These complaints provided anecdotal information about barriers to access, but library staff needed more solid data on which to act: How often were users able to retrieve a desired article? What problems did they encounter in the process, and how often did these problems occur? An availability study was conducted to answer those questions.First described by Kantor [1], an availability study is a method for evaluating how well a library satisfies user requests and identifying barriers to satisfying those requests. An availability study consists of the following steps:

1. gather actual user requests (or simulate them)
2. try to fill those requests using the same tools and methods a user would use
3. record what happens
4. analyze the results

     

E-Journal Cataloging in an Age of Alternatives: A Survey of Academic Libraries

This article reports on a survey of U.S. academic libraries that was conducted in the spring of 2008 to determine if and how academic libraries were actively cataloging e-journals in the age of the OpenURL, A–Z journal lists, and the batch loading of purchased MARC records.

SFX Statistical Reports: A Primer for Collection Assessment Librarians

SFX, an OpenURL link resolver, was implemented at the University of Illinois at Urbana-Champaign Library in late 2005. Data from the SFX statistical reporting package are providing yet another look at how library users navigate and utilize electronic resources. However, unlike other statistical reports, such as electronic use statistics provided by vendors, SFX data cover both successful and unsuccessful links, meaning that libraries can identify items patrons wanted, but which were not (for some reason) available. And while SFX cannot totally replicate use data from publishers (since it cannot track bookmarked links resulting from use outside the library's links), it can provide statistical use data in place of publishers who simply do not offer this service, which often includes smaller or more specialized publishers. SFX data also cover multiple databases and vendors, combining use and nonuse data in one statistical package. This paper provides an overview of the 20 established statistical reports available through the SFX statistics module. Suggestions are offered for how the data from these reports can be used to answer questions about how academic journal collections and their indexes are being used and what users need but are not finding.     

What is a Library?: International College Students' Perceptions of Libraries

This study presents findings from an online survey and series of one-on-one interviews with students at New York University Abu Dhabi (NYUAD) regarding their perceptions of libraries. With an international student population, NYUAD represents a unique opportunity to gain insight into a wide variety of student opinions and experiences of libraries. The goal of the study was to develop a student-based perspective of libraries, which can be used to improve library services and outreach. The student responses ranged from intense engagement with libraries to little or no experience. In general, students had a limited view of the role of librarians in the library. Interestingly, many students have a lofty view of libraries and see them as repositories of knowledge for humanity.     

Hacking the Collection: Changing the Collection in Response to a Migration

Abstract

In 2016, the Munday Library at St. Edward’s University migrated to a new discovery layer. The Library had been an EBSCO Discovery Services (EDS) customer for six years, and the migration to Ex Libris’s Alma-Primo negatively impacted content discovery and collection usage due to issues with EBSCO’s proprietary metadata and Primo’s OpenURL link resolver. This article discusses switching the library’s collection using collection data analysis to respond to the change in discovery layer. The data-informed changes made to the collection improved collection usability and access.

Raising the bar: the importance of hospital library standards in the continuing medical education accreditation process

The Connecticut State Medical Society (CSMS) reviews and accredits the continuing medical education (CME) programs offered by Connecticut's hospitals. As part of the survey process, the CSMS assesses the quality of the hospitals' libraries. In 1987, the CSMS adopted the Medical Library Association's (MLA's) "Minimum Standards for Health Sciences Libraries in Hospitals." In 1990, professional librarians were added to the survey team and, later, to the CSMS CME Committee. Librarians participating in this effort are recruited from the membership of the Connecticut Association of Health Sciences Librarians (CAHSL). The positive results of having a qualified librarian on the survey team and the invaluable impact of adherence to the MLA standards are outlined. As a direct result of this process, hospitals throughout the state have added staffing, increased space, and added funding for resources during an era of cutbacks. Some hospital libraries have been able to maintain a healthy status quo, while others have had proposed cuts reconsidered by administrators for fear of losing valuable CME accreditation status. Creating a relationship with an accrediting agency is one method by which hospital librarians elsewhere may strengthen their efforts to ensure adequate library resources in an era of downsizing. In addition, this collaboration has provided a new and important role for librarians to play on an accreditation team.     

Cooperation strengthens small hospital libraries in a rural area of New England: a five-year experience.

Before 1970, library facilities and services at the small hospitals in rural Vermont were essentially nonexistent. Similar findings were later encountered along the Connecticut River in New Hampshire and in a small area of upstate New York. The Hospital Library Development Services program was established at the University of Vermont's Dana Medical Library to improve these conditions. Financial assistance was received from the National Library of Medicine, and by the end of 1974, thirty-three hospitals had staffed libraries. Earlier that year it has been decided to begin emphasing cooperation among the developing libraries, including the production of union lists and regular meetings of staff members from geographically proximate hospital libaries to plan and implement various activities. An additional one-year award from NLM was received in 1975. Results achieved during and after the period of grant support are reported. Cooperation among hospital libraries is seen as a feasible and beneficial undertaking provided that the participating libraries are internally supported and developing.
