The Wedge is a 1944 book of poems by American modernist writer and poet William Carlos Williams.
 He assembled this collection in response to requests from American servicemen during World War II for a pocket-sized collection of his work to take into deployment with them.
 Despite the poet's inquiries and the nature of the requests that prompted him to approach them, several publishers rejected "The Wedge".
 Their grounds for doing so were a perceived lack of literary quality and wartime shortages.
 The book was eventually handset printed by Henry Duncan and Wightman Williams at Cummington Press and bound surreptitiously on the premises and at the expense of one of the publishers who had previously rejected it.
 The book is dedicated to poet Louis Zukofsky, who helped Williams revise and rearrange the poems for publication.

The objectivist poets were a loose-knit group of second-generation Modernists who emerged in the 1930s.
 They were mainly American and were influenced by, amongst others, Ezra Pound and William Carlos Williams.
 The basic tenets of objectivist poetics as defined by Louis Zukofsky were to treat the poem as an object, and to emphasise sincerity, intelligence, and the poet's ability to look clearly at the world.
 While the name of the group is similar to Ayn Rand's school of philosophy, the two movements are not affiliated in any way, and are, in fact, radically different.
