Research Information recently published a nice article: Networking sites help align publishers with customers. This features sites that SAGE and Nature Publishing Group have developed to engage with their customers.
Here is an extract that introduces the concepts:
Over the past two decades the world of academic publishing has changed beyond all recognition. We’ve gone from a world dominated by the physical journal on library shelves, to a world where not only are the journal articles available on the web via subscription, but often for free in institutional and subject repositories. The journal article also faces competition for attention from an increasing quantity of grey literature. This is not only technical papers, working papers, preprints and reports, but also less formal forms of user-generated content. Publishers need to find new ways of engaging with their users if they are to continue to be relevant.
The article goes on to review SAGE’s Methodspace site and Nature Network.
