Eleanor Gehres, who spent 25 years as head of the Denver Public Library's Western History/Genealogy Department and made it the institution it is today, is gone -- but very far from forgotten. Before her death from cancer last year, she had almost finished a massive mission: determining the "best" fiction of the twentieth century. Golden-based Fulcrum Publishing finished the job for her. The result, The Best American Novels of the Twentieth Century, Still Readable Today, is itself eminently readable, an impressive lineup of 150 terrific books, complete with Gehres's assessments and profiles of authors ranging from John Steinbeck to Jane Smiley.
