Dear colleague, This message is intended to draw your attention to the second announcement of the IFIP WG8.1 International Working Conference "INFORMATION SYSTEM CONCEPTS: An integrated discipline emerging" Lorentz Center, Leiden, The Netherlands 20-22 September 1999 http://www.wi.leidenuniv.nl/~verrynst/ISCO4-f.html Important dates: Submission of Papers/Proposals: 15 April 1999 Notification of acceptance: 15 June 1999 Camera-ready papers: 15 August 1999 We apologise if you receive this e-msg more than once, which is not unlikely since your address will have appeared on a number of lists of people interested in the theory and practice of information systems. This list is intended to be used sparingly, for reminders and conference joining instructions. Should you wish to be dropped from it (which we hope you will not), just reply with a brief word. Should you like to contact others or circulate information of interest to the other list members, again, just submit. Meanwhile, wishing you a Happy Christmas and a Prosperous New Year! Alex Verrijn-Stuart ISCO4 Organization Committee Chair Leiden, 15 December 1998 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
