For us this is a special issue at a particular moment: the journal Evaluation is marking its 20th anniversary, an occasion that challenges us to stand back and take stock -and to do so in a more nuanced way than the Social Science Citation Index on its own allows. 1 It offers an opportunity to reflect on the aspirations that launched Evaluation back in 1995, on where we are now, and where we might be going. As the editors of this special anniversary issue have all been active protagonists since the journal's launch, we are well placed to give an account of ourselves -even though many of our editorial priorities, developed in dialogue with authors, referees and readers, have only become clear to us through a rear-view mirror.
