I would like to find good models for making historical demographic data available online and information about organisations with an interest in historical demography
About historical demography the recently published book on The future of historical demography will be the best ressource for you. You will find here enclosed this volume edited by Koen Matthijs, Saskia Hin, Jan Kok, and Hideko Matsuo, in which historical demographers develop the new tools and new appraoches for this science. I was one of them and wrote a paper on Dead ends and new paths in historical demography.
