We are glad to announce the publication of the two volumes of the Kalton Selecta by Birkhauser, in the series ``Contemporary Mathematicians ». These two volumes (of about 780 pages each) gather 43 articles written by Nigel Kalton (1946-2010), sometimes with co-authors, with comments by experts of the many fields to which Nigel contributed, namely: F. Albiac, J. L. Ansorena, P. H. Enflo, D. H. Fremlin, A. Kaminska, B. Maurey, R. J. Elliott, F. Gesztesy, T. Kucherenko, G. Lancien, V. Peller, P. Portal, F. Sukochev, S. A. Ivanov, N. K. Nikolskii, I. E. Verbitsky, L. Weis, Y. A. Brudnyi, S. J. Dilworth, D. Kutzarova, Y. Benyamini, J. M. F. Castillo, H. G. Dales, M. I. Ostrovskii, G. Pisier, D. Werner, M. Cwikel, M. Milman, R. Rochberg, S. J.Dilworth, S. J. Montgomery-Smith.

These Kalton Selecta are not only a tribute to an outstanding mathematician and his formidable contribution to functional analysis. They constitute a work in which every article is explained and put in its proper framework, in such a way that the reader gets easy access to advanced theories, through the efforts of the contributors. Their appearance is a scientific event for experts and beginners alike. Nigel Kalton’s work is a gold mine for anyone who is ready to read his lines - and in between.
