I'd like to announce the availability of a survey and research article "Foundations of nominal techniques: logic and semantics of variables in abstract syntax" providing an overview of the applications of nominal sets semantics to syntax-with-binding. This is due to appear in the Bulletin of Symbolic Logic. However, I am told that it may be some months before the article appears on paper. Until then it is available online here: http://gabbay.org.uk/papers.html#fountl Murdoch Gabbay
