Today, the Institute for Scientific Information released its annual Journal Citation report, which includes Journal Impact Factors 2004. The Journal Impact Factor is calculated as the number of citations in a given year (2004) to articles published in the two preceeding years (2002-2003) divided by the number of articles published in the two preceeding years (2002-2003).

In the chemistry section, the 2004 impact factor of Angewandte Chemie is 9.161 (up from 8.427 in 2003—the highest ever), Chemistry—A European Journal celebrates not just its 10th anniversary, but also an increase from 4.353 to 4.517. Their sister journals ChemPhysChem and ChemBioChem enjoy results of 3.596 (2003: 3.316) and 3.474 (2003: 3.992), respectively, to confirm the success on their way to becoming premier international journals. The Journal Impact Factors of European Journals of Organic and Inorganic Chemistry are at 2.426 (2003: 2.227) and 2.336 (2003: 2.482). Advanced Synthesis & Catalysis rises to 4.482 (2003: 3.783).

For comparison: J. Am. Chem. Soc.: 6.903, Chem. Commun. 3.997,
J. Chem. Phys. B 3.834, Phys. Chem. Chem. Phys. 2.076,
J. Biol. Chem. 6.335, Biol. Chem. 3.598.

On the materials side, the impact factors of Advanced Materials, Advanced Functional Materials, and Chemical Vapor Deposition have also climbed significantly: 8.079 (2003: 7.305), 5.679 (2003: 4.798), and 2.209 (2003: 2.071).

For comparison: Nat. Mater. 13.5, Chem. Mater. 4.103, J. Mater. Chem. 2.721.

The publishers would like to take this opportunity to thank all authors, referees, and readers for their continued trust and support.
