uplift in downloads at the publishers’ web sites. This is likely to be the result of high quality PEER
metadata, a liberal attitude towards allowing search engine robots to index the material, and the
consequently higher digital visibility that PEER creates for scholarly content. Overall, the publisher
uplift was 11.4% (95% confidence intervals (CI95), 7.5% to 15.5%) and was highly significant (</span><span style="font-size: 11.000000pt; font-family: 'Calibri'; font-weight: 700; font-style: italic" class="">p </span><span style="font-size: 11.000000pt; font-family: 'Calibri'; font-weight: 700" class=""><

used an RCT design to investigate the impact of institutional repository exposure on publisher
downloads, albeit for a single journal (Sho and others 2011).</span></p><p class="">Food for thought.</p></div></div></div></div></div><div class="">Laurent</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">Le 22 oct. 2015 à 15:42, David Prosser <<a href="mailto:david.prosser@rluk.ac.uk" class="">david.prosser@rluk.ac.uk</a>> a écrit :</div><br class="Apple-interchange-newline"><div class="">

Marc’s post reminds me that there was the EC-funded, STM-run PEER project that attempted to do exactly this comparison:

<div class="">One of the aims of PEER was to discover the effect of Green OA on journal viability - for the journals that took part there were no negative effects on their viability. </div>
