Thank you all for your replies to my previous post. My conscience is clearer now! I adopt the same approach as gillywilly97. Knowledge, reference books, computer. Otherwise the books would have to go and I can't do that. Thanks goodness for AB though. It's nice to know I'm not the only obsessive. My girlfriend thinks I'm nuts. BB PS is there a word to describe people addicted to crosswords? And if not, can someone make one up!
