In this issue

This is a special issue based on extended papers that were originally presented at the 14th Working Conference on Reverse Engineering (WCRE 2007). The guest editors of this special issue, Massimiliano Di Penta and Jonathan Maletic, provide an introduction to these selected papers from WCRE 2007. I would like to thank the editors for all their hard work in managing the selection and reviews of these papers. I hope you find these papers interesting. Please let me know if you have any suggestions or comments on this issue.
