Introduction
Sometime mid 2017 the COLT 2010 proceedings went offline. Fortunately, we were able to retrieve the contents of that website and rehost it on the ACL server learningtheory.org. As the COLT proceedings are sometimes a little hard to find, here is a list of links to the proceedings of the most recent gatherings.
