You hold in your hand the first omnibus edition of Sunday-size crossword puzzles from the "Chicago Tribune," edited by Wayne Robert Williams. These 250 crosswords capture the flavor of Chicago perfectly-some are contemporary, some are traditional, and most fall somewhere in the middle. The puzzles are written by constructors all over the country, from California, Illinois, Massachusetts, and all points in between. In other words, they are as wonderfully diverse as Chicago itself!
