The present volume of Science, Technology & Society (STS) is special in many ways. First, the journal in the past has not published many papers on the issues related to Public Understanding of Science (PUS). The deficiency of the past is being corrected by giving a heavy dose of eight articles that cover almost the entire gamut of issues that constitute the area designated as PUS. Second, out of eight articles that are included in this volume, seven were presented at the international meeting which was held in March 2008 at Delhi. The conference, ‘Mapping the Scientific Consciousness’, was a step towards taking stock of the developments, gap-areas and future trends. It was the first PUS conference ever held in a developing country. Third, the publication almost coincides with twenty-five years of PUS research. Some of the contributors could legitimately claim to be pioneers and veterans of research in this area of scientific investigation.
