Barnett M.S., Lewis T. Outliers in statistical data

Wiley, 1978. — 188 p.This book is the standard text on the subject. The work is scattered throughout the literature of the XX century, shows no sign of any abatement, but has not previously been drawn together in a comprehensive review. In offering such a comprehensive overview of the principles and methods associated with outliers the authors hope that they may help the practitioner in the analysis of data and the researcher in opening up possible new avenues of enquiry.
