Unobtrusive methods in social research

"In this book you will discover how data can be 'found' in the world, captured from different forms of observation and retrieved from data banks of various kinds. There is a particular focus on use of the Internet, which promises to be a major source of unobtrusive data. You will learn how to generate unobtrusive measures, and also look at some of the wider ethical issues raised by the use of unobtrusive data."--Jacket.
