I am very pleased to introduce a new journal, Transactions of the Association of European Schools of Planning. A first question may arise to the reader: is there a need for another planning journal? Indeed, although the planning discipline developed in the twentieth century, it remains rather young, and today there is a number of very good journals. However, after vivid discussions, AESOP has come to the conclusion that the project of Transactions, developed with a remarkable dedication by Ela Babalık-Sutcliffe, Andrea Frank, Nikos Karadimitriou and Olivier Sykes, is to provide our community with something complementary to existing journals: unique and precious.
