Just in case you’ve not yet heard about this, the folks in Windsor have done us all a great service. The proceedings of all OSSA conferences from the very first to the most recent are now available online at the OSSA Conference Archive. Papers and commentaries are available for viewing and download. Search options are up-to-date too. For those of us who want to cite these papers in our work, this is an indispensable and easy-to-use resource that compares favorably with the ISSA Conference Archive maintained by Rozenberg Quarterly. Both are laudable additions to the online resources available for argumentation researchers.

Hello! I worked with Hans Hansen, Cate Hundleby, Chris Tindale and others to setup the archive for Windsor. I’m extremely happy to see that it is being well used and appreciated! If there are any features or issues please let us know. The last remaining piece of the puzzle is the remaining 5% or so of papers that are under restricted access awaiting author permissions. Looking forward to adding OSSA 11.
