This book is a collection of papers presented in Stockholm, at the fourth Critical Link conference. The introducing article explicitly addresses the issue of professionalism and how this has been dealt with in research on interpreting. The following two sections provide examples of recent research, applying various theoretical approaches. Section four reports on the development of current, more or less local standards. Section five raises issues of professional ideology. The final section tells about new training initiatives and programmes. All contributions were selected because of their relevance to the theme of professionalisation of interpreting in the community. The volume is the fourth in a series, documenting the advance of a whole new empirical and professional field..
