This book constitutes the thoroughly refereed post-proceedings of the 13th International Conference on Implementation and Application of Automata, CIAA 2008, held in San Francisco, USA, in July 2008. The 26 revised full papers togehter with 4 invited papers were carefully reviewed and selected from 40 submissions and have gone through two rounds of reviewing and improvement. The papers cover various topics in the theory, implementation, and applications of automata and related structures.
