Conclusions
• Document delivery grows linearly.• Article reads grows exponentially (true
exponent).• Probably because more users site-
licensed and more libraries set up e-access.
• Didn’t you do well!
User Friendly
• Assuming whole world isn’t eventually site-licensed, then will always need some means of document purchase to prevent the “Blank Wall.”
• Should make all references go somewhere positive, not just a location with a tantalising piece of information, with no option to go further.
• Should always link to a place that offers document purchase options.
• But not just one supplier – don’t limit yourself!
CrossRef Success
• Initial success has been a PR success, not an end-user success.
• Succeeds in long term if users happy.• Means every reference in every
document must link somewhere.• Therefore publishers must link out as
well as in!

Conclusions
• Only 0.02% of catchword document reads come from users following reference links from other sites
• 0.3% of users reading an article follow a link to another site
• Not everyone is playing ball!
Future of Reference Linking
• If users find that only some CrossRef publishers/resources have two-way linking, the reference-linking concept will not catch on.
• Don’t let that happen!• Activate links!• Activate purchasing options, or will never know
true potential of document sales.• Outsource linking and e-commerce to keep
costs low.
OpenURL
• Implementing links out with OpenURL compliance gives librarians and hence users further options instead of the potential “blank wall”.
• Worried about OpenURL?• Limit or at least monitor full-text
database licence deals, e.g. Sage.
Conclusions and Recommendations
• Article economy for electronic documents relatively small due to site licences.
• Even so, for CrossRef to succeed, every reference needs to go somewhere – full text or A&I or traditional document delivery – no blank walls please!
• Outsourcing of e-commerce and linking are real options.
