Dear All, I would like to communicate some information on the "Cahiers". 1. Last year, prompted by several people, in particular Ronnie, I had asked for the inclusion of the "Cahiers" in the ISI database, and I was informed that the assessment process required about 1 year. The answer arrived in August: it is rejected. As I was surprised, all the more since I thought TAC had been accepted, I asked for the reasons. I join the answer at the end of this msg. 2. The "Cahiers" show that a journal need not be very expensive. It costs 82 euros a year, and lives on its subscriptions (almost all by foreign universities) which entirely and exactly cover the expenses: printing of the final pdf file which I give to the (commercial) printer, envelopes and stamps I use for snail mail delivery. It should be noted that there is no staff expenses since, without any financial nor material support, I myself edit the complete file (with the help of the authors who kindly comply with my format requirements?), and manage the subscriptions, the packing up and sending of the volumes. I am sorry of the ThomasReuters decision which might be a prejudice for the authors, I'll try to have it reversed in the future if it is possible, and I hope you all will help me.

We examined the citation record of the Cahiers for both 2009 and 2010. (The 2010 citation data became available just a few months ago). The citation data for both years show that the citation rate for the Cahiers was very low - even lower in 2010 than in 2009 - and did not compare favorably with other core mathematics journals indexed in the database, in particular, journals covering the subject areas of topology and category. Theory and Applications of Categories was indeed added to the database earlier this year and during its evaluation demonstrated a much stronger citation rate. Many high impact journals covering the field of topology, such as Topology and Its Applications, Topology and Topological Methods in Nonlinear Analysis, are also indexed in the database. Thus, these fields in mathematics are well represented in the database. We would be pleased to arrange a reevaluation of the journal in 36 months, if you care to contact us again at that time. (In the meantime, it is not necessary to send us further issues.) Further exposure to the research community, new quantitative data and our evolving coverage priorities may yield a different decision.
