Why Quality Search Engines do not support Z39.50
• Z39.50 is difficult to implement
• No control over what is presented to the user
• No high demand for Z39.50 access

Conclusions
• Quality Search Engines should adopt Z39.50 or SRW and OpenURLs
• SRW is still under discussion; owners of QSE’s must join the discussion now
• Libraries must convince publishers and aggregators of the above; issue in license negotations

Conclusions continued
• It must become possible that OpenURLs return context info.
• Information portals must make optimal use of the possibilities that will offered to them.
