Dear SIGCIS-members, A while ago there was a thread on methodologies developed in other branches of the history of science that could be useful to the history of computing. For the last 20 years much work has been done on the history of algorithms, mostly within the history of mathematics, and quite some interesting new ideas and methods have come from this rich and vibrant field. On the occasion of a new edition of a 1995-book on the history of algorithms (that is now a bit old-fashioned), I wrote an essay review that gives an overview on what has been happening these last 20 years. The essay review just appeared in Historia Mathematica and can be freely downloaded until September 2nd using this link, http://authors.elsevier.com/a/1TNB117f6j-t2L I hope this may be useful to some list members. best regards, Maarten Bullynck Département de mathématiques & histoire des sciences Université Paris 8
