Why do some results not include a link directly to the article (or whatever) in the database?

Some databases (OCLC, for instance) do not currently support stable title-level linking to abstract content or bibliographic records, only to full-text content. This means that 360 Search cannot build a link to non-full-text results; users can only access the content by clicking on the Source link and searching in the native interface for it, or by using SFX to see if the full-text content is available in another database.
