Are we losing print subscriptions?

Additional revenue

Research Impact

Is it due to OA?

• 558 authors who cited articles• 68% from PubMed, 10% from web• 63% used an OA source for full text• If not OA– 35% would not have quoted article– 26% would have quoted on basis of abstract – <5% would pay for access

Conclusions

• For a journal, open access– helps to improve visibility 

– helps to attract authors– helps to improve quality

– helps to increase research impact

– does not affect subscriptions
