Linking: An Overview North Carolina Serials Conference Chapel Hill, NC April 4, 2003
Critical Elements • Clean metadata • So content can be found, cataloged, interpreted, USED • Allows for consistent use of terms so making associations are practical • Co-operation • The more participation and agreement on standards, the more useful content becomes • Competition • Healthy; means of encouraging continuing attention paid to user needs, product/service development
Why Link? • Disseminate content as widely as possible • Distribution of metadata (rather than full text) to gateways, databases, portals, etc – easing discovery • Increased visibility to diverse user groups • Make content as functional as possible • Reference resolution: find resources holding cited article; created “on the fly” to ensure currency • Forward citations: link to succeeding articles which refer back to it • Make links as intelligent as possible • Appropriate copy issues
Publisher/agent/ secondary publisher/ et al co-operation needed to build as comprehensive a network as practical Different links needed for different groups – intermediaries with subscription activation programs can help with pre-authentication to speed access to full text Content Dissemination • The Wish • The web provides users with a simple online interface through which they can seamlessly access all online journals. • The Reality • No one entry way exists, and besides, users favor different starting points… • …So we need to ensure content is available through as many as possible
CrossRef • Perhaps the most significant industry development in recent years: • Provides a repository of metadata (DOI) – like a directory of mobile phone numbers, with automatic dialing • Creates persistent, sustainable links to content, ensuring long-term access to information regardless of location or status of owner • A multi-publisher initiative enabling the linking of references to the cited full text • Facilitates both inbound and outbound linking
Active References user follows link from citation in full text …
On-the-Fly Resources … to external resources page: follow link …
Direct Links … to view result on chosen service
Appropriate Copy • Context-sensitive linking • Allows greater control over what resources are available to users: shows users • Appropriate copy • Most immediately available copy • Link servers • Software enabling context-sensitive linking – helps makes links more useful by filtering as appropriate
