Title

Journal production and journal impact factor

There exists a direct linear relation between journal production and impact factor. The more articles a 'normal' journal publishes, the larger its impact factor. Review journals and translation journals are clear exceptions to this rule. The field of mathematics and chemistry seem to be large scale exceptions
