This book presents a comprehensive study of advice-giving in one particular American Internet advice column, referred to as ‘Lucy Answers’. The discursive practice investigated is part of a professional and educational health program managed by an American university. The study provides insights into the linguistic realization of both asking for and giving advice in a written form and thus adds to the literature on advice columns as a specific text genre, on advice in health care contexts, and on Internet communication. The book offers a comprehensive literature review of advice in health encounters and other contexts, and uses this knowledge as a basis for comparison. Advice Online demonstrates how qualitative and quantitative research methods can be successfully combined to arrive at a comprehensive analysis of a discursive practice.
