The National Puzzlers' League, founded as the Eastern Puzzlers' League in New York City in 1883, is devoted to the creation and solution of versified word puzzles, as popular in the nineteenth and early twentieth centuries as crosswords and cryptograms are today. In the fall of 1998, the League privately published The National Puzzlers' League--The First 115 Years, a 380-page bound volume issued free (upon request) to its members and available to others for $14 plus postage (the editor has copies available).
