James Thurber has had official honors. But “despite all this official appreciation, a doubt arises: Is Thurber still being widely read and enjoyed? The nod from the Library of America was meant as a coronation, but nobody can be funny for a thousand pages, and Thurber’s writing—occasional by definition—resists so exhaustive and formal an act of exhumation and canonization. As for the new collection of his letters, your pleasure in it will probably depend on how much of the Thurber literature you’ve been exposed to — I mean the literature about him, not the literature by him.”
