3. Benefits of context-sensitive linking Users have easy access to library’s entire online collection.
Library can offer users access to local print holdings.
Library can offer users others services, e.g. Interlibrary Loan, other search options.
4. Linking Options Database provider linking services
Subscription-based, hosted linking services
Local link resolver products
5. Database provider linking services Examples: WilsonLink, Links@Ovid
Available at no extra charge
Provides linking to fulltext internally in their databases and externally to other publishers and content aggregators
Disadvantage: Must create and maintain file of library’s journal holdings for each database provider.
6. Subscription-based, hosted linking services Examples: Ovid LinkSolver, EBSCO LinkSource, Serials Solutions ArticleLinker, Openly Informatics 1cate
Price: usually based on FTE
Works with any OpenURL-enabled database
Create and maintain one file of the library’s journal holdings
Reliance on vendor to add titles and link-to syntax. Mortality and Morbidity Weekly Report included in database but not Emerging Infectious Disease.Mortality and Morbidity Weekly Report included in database but not Emerging Infectious Disease.
7. Local link resolution servers Examples: Ex Libris SFX, Fretwell-Downing OL2, Sirsi Resolver, Innovative Interfaces WebBridge, Endeavor LinkFinderPlus
Linking products are usually stand-alone systems running on separate hardware.
Works with any OpenURL-enabled database.
Create and maintain one file of the library’s journal holdings.
Library controls when updates and changes are made to journal holdings and links.
8. Factors to consider in selecting linking service Benefits to users
Technology that is the best match for your institution: remotely hosted service or support for a link server
Staffing
Costs
Current licensed databases (Are they OpenURL-enabled?)
Fulltext content resources
9. Evaluating linking services Quality of database controlling linking
Does the database include your libraries fulltext resources?
How frequently are updates made to the database?
What is the process for the library to request additions and changes?
10. Evaluating linking services (continued) Is the vendor partnering with other vendors for linking?
Does the vendor offer an import utility for loading journal holdings from the OPAC or a serial vendor?
What options does the vendor provide for customization?
11. Evaluating linking services (continued) What options does the vendor provide for allowing the library to link users to the “appropriate copy” when there are multiple resources with the fulltext?
Can the vendor under consideration can sustain this service?
12. Conclusion Linking is a rapidly evolving technology.
New linking products and services continue to be announced.
Emerging OpenURL standard is an important development for libraries and information industry.
Biggest problem and continuing challenge for linking is the need for quality metadata to dynamically compute links, which makes unique identifiers (e.g. DOI) for information objects critical.
