Computer Science Logic 22nd International Workshop, CSL 2008, 17th Annual Conference of the EACSL, Bertinoro, Italy, September 16-19, 2008, Proceedings

The annual conference of the European Association for Computer Science Logic (EACSL), CSL 2008, was held in Bertinoro, near Bologna (Italy), September 16 19, 2008. The conference series started as a program of International Wo- shops on Computer Science Logic, and then at its sixth meeting became the Annual Conference of the EACSL.

CSL2008wasprecededonMonday, September15thbythesymposiumBri- ing Logic and Computer Science on the occasion of the 60th birthday of Johann A. Makowsky. In response to the call for papers, a total of 102 abstracts were submitted to CSL 2008 of which 87 were followed by a full paper. The Program Committee selected 31 papers for presentation at the conference and publication in these proceedings, during a one-weekelectronicdiscussion on the EasyChairplatform; each paper was refereed by three to ?ve reviewers.
