This page collects links to proceedings for the Conference on Learning Theory (COLT) as well as the European Conference on Computational Learning Theory (EuroCOLT).
COLT was previously called the Workshop on Computational Learning Theory and the Conference on Computational Learning Theory.
COLT and EuroCOLT merged in 2001.
Several of these links were obtained from the dblp listings for COLT and EuroCOLT.
Another wonderful resource is The Bibliography on Computational and Algorithmic Learning Theory.
