On June 20th, ISI Web of Knowledge released the list of impact factors of all journals. Despite its obvious shortcomings, authors and editors fight over a high impact factor for their journal. This year, a five year impact factor and the eigen factor was also mentioned for each journal.
The top three journals in chemical engineering, AIChE Journal (published by Wiley), Chemical Engineering Science (published by Elsevier) and Industrial and Engineering Chemistry Research (published by American Chemical Society) all tied with nearly the same impact factor of 1.89. The three other journals to which I regular submit namely Journal of Physical Chemistry B, Applied Catalysis B and Polymer Degradation and Stability all show an increase in the impact factor compared to last year.
