"Beats Poets," a snug volume of various poetry from the Beat era in the 1950s and 60s, can serve as a sampler for 28 modern influential poets.
Passages from Ginsberg's "Howl" and Corso's "Transformation & Escape" will draw you read these pieces in full. "Howl" is the highly controversial poem which challenged free speech and the definition of art.
Creeley, Jones, and O'Hara are hear, as is Lawrence Ferlinghetti, both poet and owner of the famous San Francisco bookstore "City Lights" where so much of the Beat movement originated.
Denise Levertov is notably here with five selections. Only a few Kerouac poems are published here, but his work can be easily found in larger collections.
Helping capture the Beat movement, editor Carmela Ciuraru has included "Letters, Encounters and Statements on Poetics," which is a collection of short essays by a few of Beat's major players.
I fully recommend "Beat Poets."
