The Emeralds Encyclopedia, informally dubbed the "Em's-cyclopedia," chronicles every year of Eugene Emeralds history starting with the Eugene Larks of the 1950's, to the Emeralds inaugural season in 1955, all the way through 2021. The Emeralds Encyclopedia includes full team stats from every Em's season, photos that have not seen the light of day in decades, press clippings and box scores, player profiles, game programs, and countless memories built at Bethel Park, Civic Stadium, and PK Park.

Never before has a book been so meticulously crafted to portray the in-depth history of a Minor League Baseball team.

Author Chris Rohaley and former Register-Guard writer Steve Mims crafted this one-of-a-kind encyclopedia that will bring you blasts from the past with each turn of the page. From winning the league title in the team's first-ever season to the Triple-A days, when Hall of Famer Mike Schmidt patrolled third base at Civic Stadium, to the introduction of Los Monarcas de Eugene.  Every major moment in Em's history is noted in this incredible literary work.
