Howard J. Citation by citation, new maps chart hot research and scholarship's hidden terrain. The Chronicle of Higher Education 2011, Sept. 11
A team led by two biologists and a physicist has set out to build a guidance system, a sort of Google maps of scholarship, to help researchers locate hot research, spot hidden connections to other fields, and identify new disciplines. The Eigenfactor algorithm should take into account the sources of citations. This tool should be freely available and run on a desktop or laptop computer.
