how url s fail
How URL’s fail

target

  • User's library doesn't subscribe to target
  • target authenticates by IP, user is off campus
  • User's library gets target item in a full-text aggregation
  • User's library has a locally hosted copy of target journal
  • User's country has a nationally hosted copy of target journal
  • target has moved its content without telling source
  • target has become a porn site

This is known as the "Appropriate Copy Problem"

The link server lets the library fix these problems and determine which copy is appropriate
