I read with interest your editorial "The Impact Factor Game". In a letter titled "Sprucing up One's Impact Factor" published by a colleague and myself in Nature in 1999 (401:321-322), we had indeed made much the same points as you have in highlighting the importance of the denominator in calculating the impact factor of different journals, and how some articles not counted as "source" items for the denominator had received large numbers of citations and so boosted the concerned journal's impact factor.

We had also remarked on possible methods to enhance the numerator value, such as by the inclusion of minireviews in research journals as well as by the practice of encouraging authors to cite other papers in the same journal. I do hope that the addition of your important voice in this debate will have the necessary effect in making the system more transparent and accountable.
