Hello fellow sigcis'ers, I currently work on a speech for the Danish Society for the History of Technology. My working title is 'Software - the historical study of an immaterial technology', and I attempt to a) give an introduction to the field, software history, and b) discuss the challenges of working with software history. I know of this very comprehensive bibliography of software history (http://www.cbi.umn.edu/research/shbib.pdf - thanks to those who made it!!) and I think that I have an overall good overview of the litterature on the subject. Nervetheless, I figure that some of you might have a favourite article, a must-read suggestion or have just worked with the matter of software history and historiographical challenges? If this is the case, please, do not hesitate to send me suggestions for further reading, - I prefer a suggestion that I might already have thought of, than no suggestion at all! Thank you very much, have a joyfull Monday The best regards Julie
