  6. 3. Link Resolver - SFX • Menu or Direct Linking? • Menu advantages: display alternatives provide more information • Menu disadvantages: slows the user down more mouse clicks

  7. SFX cont. • Direct Linking Advantages: • rapid, seamless progression to the target article • (near) instant gratification Disadvantages: • Doesn’t exploit multiple FullText targets • Bypasses other library services
