The Empire Strikes Back

Publishers may soon compete with libraries. The business case for enticing users away from library-managed portals is simple, compelling, and growing. As funding agencies and universities enact Open Access (OA) mandates and publishers transition their journals from the site-license model to the Gold OA model, libraries will cease to be the spigots through which money streams from universities to publishers. In the Gold-OA world, the publishers' core business is developing relationships with scholars, not librarians. For publishers, it makes perfect sense to cater to scholars both as authors and readers. (...) Publishers, indexing services, journal aggregators, startups, some nonprofit organizations, and library-system vendors all have expertise to produce compelling post-OA services. However, publishers only need to protect their Gold OA income, and any new revenue streams are just icing on the cake. All others need a reasonable expectation of new revenue to develop new services. This sets the stage for a significant consolidation of the scholarly-communication industry into the hands of publishers.

Publishers offer their “solution” to public access

CHORUS (for ClearingHouse for the Open Research of the United Status) is clearly an effort on the part of publishers to minimize the savings that will ultimately accrue to the federal government, other funders and universities from public access policies. If CHORUS is adopted, publishers will without a doubt try to fold the costs of creating and maintaining the system into their subscription/site license charges – the routinely ask libraries to pay for all of their “value added” services. Thus not only would potential savings never materialize, the government would end up paying the costs of CHORUS indirectly.
