Invited articles section foreword

This issue inaugurates the Invited Articles section of JACM. Each year, JACM invites a small number of articles to appear in the journal based on the recommendation of the Program Committees of several major conferences in Computer Science. All invited articles are reviewed according to the standard JACM refereeing process. In this issue, the Invited Articles section is comprised of the article “Epistemic Privacy” by Alexandre Evfimievski, Ronald Fagin and David Woodruff, selected from the 27th ACM SIGMOD-SIGACT-SIGART Symposium on Principles of Database Systems (PODS), held in Vancouver, Canada, June 9–11, 2008. I thank the Program Committee of PODS 2008 and the PC Chair, Maurizio Lenzerini, for their help in selecting this invited paper.
