From the Sociology of Science to Sociological Journals: In France, in the social sciences, the evaluation of published research is a poorly structured field. But evaluation is possible when following a rigorous procedure. The method developed here by the author consists to crossing several authoritative data bases of periodicals, then constructing lists of reviews which a widely submitted to the scientific community for comment, and also to a few experts. A journal is then considered scientific when it is so judged to be by the researchers of its scientific community. A case study is proposed here conceming the field of sociology. The survey results (almost 200 French and foreigh joumals and half a thousand sociologists questioned) are analyzed here.
