Dear Sigcis members, I have questions about "Urtext Edition" of these historical papers: 1) John von Neumann, "First Draft of a Report on the EDVAC" 2) Arthur W. Burks, Herman H.Goldstine, John von Neumann, "Preliminary Discussion of the Logical Design of an Electronic Computing Instrument" Recently my colleague and I are doing translation of these papers into Japanese for publication. In order to make the translation as correct as possible, we are looking for the version that is the closest to the original one. About 1), we are using this version so far: http://www.virtualtravelog.net/entries/2003-08-TheFirstDraft.pdf It seems that this version is a finely edited one. Does anyone have the original typescript of this paper? Or does anyone know where the typescript is? About 2), we are using 'A.H.Taub, ed: John von Neumann Collected Works' and also referring this version stored at U. of Michigan: http://deepblue.lib.umich.edu/handle/2027.42/3972 Does anyone have some information on other version of this paper? I would really appreciate any kind of information about them. Thank you. Mai ----- Mai Sugimoto Ph.D Student, Program of Philosophy and History of Science, Kyoto University, Japan nix.pura@gmail.com
