As Project Manager for the PEER Project, I was delighted by the excellent multi-stakeholder participation we had at our results conference on 29 May and appreciate the efforts of many attendees at disseminating notable results via twitter, listervs etc afterwards.  Unfortunately, the statements made by David in connection with the usage research findings are misleading. Ian Rowlands of the CIBER Research group who reported on the usage results made it very clear that the usage results he was reporting were very specific to PEER and could not be blindly applied to a broader Green Open Access environment for a number of reasons. In particular, given the early stage of PEER in terms of its establishment as a repository, CIBER notes that usage observations from PEER are probably atypical of longer established Green OA repositories. 
 
Another issue is that due to the processes followed within PEER, there was strong linkage between the accepted manuscript repository versions and the Version of Record on publisher platforms via the DOI, which is often not the case, so the increase in traffic at the publisher platforms within PEER was facilitated by the particular infrastructure created for the experiment. That said, the apparent increase in traffic flow at publisher platforms within PEER does support the findings of the PEER behavioural research study that readers generally prefer to use the Version of Record.  
 
Among other notable findings from PEER was the negligible uptake of author deposit, despite invitations from publishers and the creation of a very simple centralised deposit interface with help desk support functionality, leading the PEER Executive members to collectively agree that author self-archiving is unlikely to generate a critical mass of Green OA content.  
 
The presentations from the PEER conference as well as the Executive Partner statements, reflecting on PEER and Future OA scenarios are now available on the conference page of the PEER website http://www.peerproject.eu/peer-end-of-project-conference-29th-may-2012/ 
 
Final written reports from the usage research will be available from the PEER website around mid-June.
