OPEN ACCESS PUBLISHING://STM meets Web 2.0

The open access movement in scientific publishing scores two potentially significant points:

• Gold road (journal publishing): the Public Library of Science plans PLoS ONE in 06H2. This platform will bundle research from every discipline, with added value. The latter sounds much like Web 2.0: search, tags (annotations and comments), ratings. How will this differ from ScienceDirect (from Elsevier Science)? I wonder what Stevan Harnad and Peter Suber have to say about this.
• Green road (self-archiving): a JISC-sponsored report (Linking UK Repositories) calls for a major investment in repositories infrastructure. Focus points: search, resource discovery.
