In this book, Ivan T. Sanderson summarizes current world evidence regarding ABSMs (abominable snowmen), drawing from records and reports that are world-wide in scope and cover a broad period of time. For completeness he discusses all prevailing views, both pro and con, ranging from highly plausible accounts to reports that border on the absurd. The result is as thorough an evaluation of all known ABSM sightings as could possibly be compiled at this time.
