Counting on citations: a flawed way to measure quality

The journal Impact Factor and citation counts are misconstrued and misused as measures of scientific quality. Articles must be read in order to judge their quality. We have introduced a system, which may be easily replicated, to identify the best articles published in a journal.

Gloom or glee? Each September, journal editors and publishers anxiously await news of a particular figure from the Institute of Scientific Information (ISI) in Philadelphia, USA. The figure's value is promptly met with despair or delight. We are referring, of course, to the Impact Factor (IF) and the ritual surrounding its release that has come to dominate the editors' and publishers' calendar.
