The Association of American Publishers have launched a response to the OSTP White House Executive Order on public access to publicly funded research. In this they offer to set up a registry or system called CHORUS which they suggest can provide the same levels of access to research funded by Federal Agencies as would the widespread adoption of existing infrastructure like PubMedCentral. The bottom line is that it is necessary to bear in mind that this is the same group that put together the Research Works Act, a group with a long standing, and in some cases personal, antipathy to the success of PMC. There is therefore some grounds for scepticism about the motivations of the proposal. However here I want to dig a bit more into the details of whether the proposal can deliver. I will admit to being sceptical from the beginning but the more I think about this, the more it seems that either there is nothing there at all, or alternately the publishers involved are setting themselves up for a massive and potentially hugely expensive failure. Let’s dig a little deeper into this to see where the problems lie.
