Linking Options

• Package provides a direct link automatically.
  
• You must turn on the link.

Sample Databases or programs that allow article-level linking

• Government databases: links within government website databases
  
• Cambridge Scientific Abstracts: Environmental Sciences links to IUCAT
  
• SilverPlatter databases: WebSPIRS link to IUCAT
  
• MathSciNet: direct link to many articles
  
• SciFinder Scholar: OPAC link possible through ChemPort Connection's In-house Library Option option (or direct link to the article through regular Chemport link)
  
• Web of Science
  
• SIMBAD Astronomical Database
• MDL's LitLink Server
  • allows a choice of site for the article
  • LitLink demonstration
• SFX (Special Effects): Ex Libris
  • allows context-sensitive linking (i.e., determined by the library)
  • works with Web of Science (ISI), SilverPlatter, ENSCO, ProQuest and others
  • incorporates the OpenURL standard
  • compatible with DOI and CrossRef

Standard Serial Identifiers

• International Standard Serial Number (ISSN)
• Serial Item and Contribution Identifier (SICI)
  • SICI Generator
  • Example: 1234-56789(1998)1:2:3<15:ABCDEF>2.0.TX;2-A
• Publisher Item Identifier (PII) - a unique key that specifies the article. The first 8 digits are the ISSN of the journal; the rest is typically a serial number, e.g., the manuscript number, and is usually unrelated to the volume/issue/page.
• Digital Object Identifier (DOI) - a system for interoperably identifying and exchanging intellectual property in the digital environment.
  • Examples:
    http://dx.doi.org/10.1016/S0304-4017(00)00375-7

    http://dx.doi.org/10.1016/S0025-5408(00)00447-5

• CrossRef - a collaborative reference linking service for publishers.

The APPROPRIATE COPY Problem

• Causes a problem when multiple copies of a journal title are held. What is the authoritative version (options in electronic publishing and vending)?
  1. Print is authoritative and complete (more content in print; only major or selected articles appear online).
  2. Electronic is authoriatative and complete (more content online, perhaps additional articles or data files.
  3. Neither is complete nor authoritative (need to access both for complete content).
  4. The two are somewhat equivalent, but individual articles may differ depending on the version accessed.

• the OpenURL Framework solution: an architecture that allows for the construction of localized, context-sensitive links based on metadata and identifiers for referenced works.
  • Open Linking model separates the identity of the referenced items from specific linking addresses
  • source system links to a local service component such as SFX rather than linking directly to the referenced work
  • passes information identifying the bibliographic item
