On the ‘impact factor’ in the <a href=

He eventually dreamed up something he called an “impact factor”, essentially a grading system for journals, that could help him pick out the most important publications from the ranks of lesser titles. To identify which journals mattered most to scientists, he proposed tallying up the number of citations an average article in each journal received.
This accounting method sounds harmless enough. Outside academe, few people have even heard of it. Mr. Garfield, though, now compares his brainchild to nuclear energy: a force that can help society but can unleash mayhem when it is misused.
Indeed, impact factors have assumed so much power, especially in the past five years, that they are starting to control the scientific enterprise. In Europe, Asia, and, increasingly, the United States, Mr. Garfield’s tool can play a crucial role in hiring, tenure decisions, and the awarding of grants…’
