Previous ETOPIM proceedings represent an outstanding collection of leading research that includes some landmark papers. Following this tradition the proceedings of ETOPIM6 will be published as a special issue of Physica B. The guest editors are David Dobson, Ken Golden, Graeme Milton, and Valy Vardeny. Invited speakers and participants with accepted contributed presentations are required to hand in the manuscripts before or during, but absolutely no later than, August 31st. The manuscripts will go through the usual review process. Twenty-five offprints of each contribution will be mailed, free of charge, to the first or corresponding author. Additional offprints can be ordered in accordance with the standard prices of the journal. An offprint order form will be sent to the authors together with the proofs. Further details on the preparation of manuscripts will be sent to authors with the acceptance notice.
