opuscule
n. a musical or literary work of small size

In 1965 poet Aram Saroyan wrote a poem consisting of a single word, lighght. George Plimpton included it in the American Literary Anthology, and Saroyan received a $500 cash award from the National Endowment for the Arts.

Perhaps to mock this, in 1972 Dave Morice published Matchbook, a literary magazine whose inch-square pages were stapled inside working matchbooks. Edited by the fictional Joyce Holland, each issue featured nine one-word poems submitted by contributors. Examples:

apocatastasis (Allen Ginsberg)
borken (Keith Abbott)
cerealism (Fletcher Copp)
cosmicpolitan (Morty Sklar)
embooshed (Cinda Wormley)
gulp (Pat Paulsen)
Joyce (Andrei Codrescu)
meeeeeeeeeeeeee (Duane Ackerson)
puppylust (P.J. Casteel)
sixamtoninepm (Kit Robinson)
underwhere (Carol DeLugach)
zoombie (Sheila Heldenbrand)

The longest submission, Trudi Katchmar’s whahavyagotthasgudtareedare, appeared as a fold-out.
