Brian Barry’s Literary Executors, Matt Matravers, Paul Kelly and Albert Weale, have set up a website for Brian Barry’s unpublished manuscripts, papers, and other things. The website is an ongoing project and they will be adding more to it over time. Once they have uploaded the material, they will also add comments and a better structure. In the mean time, the material is freely available, but should you cite it please cite the website.
Any comments (in particular, any information about the material) can be sent to the email address on the contact page. The address is https://sites.google.com/a/york.ac.uk/brianbarryarchive/
