Users see a Library, not a bunch of databases and a linking brand

The Library


How URL’s fail

• 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"
