This blog post by Peter Coles makes for sad reading. Clearly his field of physics is far ahead to my field with regards to open access publications in scientific practice – but for the REF the obnoxious impact factor may well skew the judgement.
In my institution, the University Medical Center, money is allocated among departments based in part on the cumulative impact factor per year. Now wonder one has to leer for IF when publishing. Consequently, #openaccess journals have a hard time to win over authors while they're still in the dry spell “no impact factor yet”.
If I had a persecution complex I would wonder why Peter's homepage in Cardiff has “limited access”…
