Dave Langford reviewed X Stands for Unknown for White Dwarf #79, and stated that "If you're scientifically literate you'll find the interesting bits buried in over-familiar stuff (though I always cheer Asimov when he stomps the crackpots). If not, you probably don't read books like this. That's showbiz."[1]
