Contributions to the History of Concepts has much to celebrate. On one hand, issue number 3 inaugurates the journal’s second volume; its second year of existence. The reception of volume one could not have been better. We have received enthusiastic feedback from readers all over the world. Contributions has published authors from many different countries and from diverse academic milieus and traditions. The international reception of conceptual history has been on the rise for decades and Contributions is both a consequence of and an agent in this process. Our celebration, however, is not without sorrow. On February 3, 2006, Reinhart Koselleck passed away. One of the most influential historians and theoreticians of the last fifty years, Koselleck was simply the most important author in the field of conceptual history and, at the same time, an active promoter of its international reception.
