WoLLIC is an annual international forum on inter-disciplinary research involving formal logic, computing and programming theory, and natural language and reasoning. Each meeting includes invited talks and tutorials as well as contributed papers. The Fifteenth WoLLIC will be held in Edinburgh, Scotland, from July 1 to July 4, 2008. It is sponsored by the Association for Symbolic Logic (ASL), the Interest Group in Pure and Applied Logics (IGPL), the European Association for Logic, Language and Information (FoLLI), the European Association for Theoretical Computer Science (EATCS), the Sociedade Brasileira de Computação (SBC), and the Sociedade Brasileira de Lógica (SBL).

Paper submission
Contributions are invited on all pertinent subjects, with particular interest in cross-disciplinary topics. Typical but not exclusive areas of interest are: foundations of computing and programming; novel computation models and paradigms; broad notions of proof and belief; formal methods in software and hardware development; logical approach to natural language and reasoning; logics of programs, actions and resources; foundational aspects of information organization, search, flow, sharing, and protection. Proposed contributions should be in English, and consist of a scholarly exposition accessible to the non-specialist, including motivation, background, and comparison with related works. They must not exceed 10 pages (in font 10 or higher), with up to 5 additional pages for references and technical appendices. The paper's main results must not be published or submitted for publication in refereed venues, including journals and other scientific meetings. It is expected that each accepted paper be presented at the meeting by one of its authors. Papers must be submitted electronically at http://www.cin.ufpe.br/~wollic/wollic2008/instructions.html A title and single-paragraph abstract should be submitted by February 24, and the full paper by March 2 (firm date). Notifications are expected by April 13, and final papers for the proceedings will be due by April 27 (firm date).

Proceedings
The proceedings of WoLLIC 2008, including both invited and contributed papers, will be published in advance of the meeting as a volume in Springer's Lecture Notes in Computer Science (tbc). In addition, abstracts will be published in the Conference Report section of the Logic Journal of the IGPL, and selected contributions will be published as a special post-conference WoLLIC 2008 issue of the Journal of Logic and Computation (tbc).
