The Twenty-Second British Combinatorial Conference was organised by the University of St Andrews. It was held in St Andrews in July 2009. The British Combinatorial Committee had invited nine distinguished combinatorialists to give survey lectures in areas of their expertise, and this volume contains the survey articles on which these lectures were based.

In compiling this volume we are indebted to the authors for preparing their articles so accurately and professionally, and to the referees for their rapid responses and keen eye for detail. We would also like to thank Roger Astley, Diana Gillooly and Peter Thompson at Cambridge University Press, and Max Neunhöffer at the University of St Andrews for their advice and assistance. Finally, without the previous efforts of editors of earlier Surveys and the guidance of the British Combinatorial Committee, the preparation of this volume would have been somewhat daunting.

We gratefully acknowledge the financial support provided by the London Mathematical Society, the Edinburgh Mathematical Society, the Glasgow Mathematical Journal Trust and the EPSRC.
