Prufrock and Other Observations is a collection of poems by T. S. Eliot, first published in 1917. The title poem, "The Love Song of J. Alfred Prufrock," is perhaps the most well-known and influential piece in the collection. The poems in this collection are considered to be early examples of Eliot's work and showcase his distinctive modernist style. "Prufrock and Other Observations" is significant for its departure from traditional poetic forms and themes. Eliot's use of modernist techniques, such as fragmentation and allusion, marks a shift in poetic expression during the early 20th century. The collection is a precursor to Eliot's later and more famous works, such as "The Waste Land," and it provides insights into his evolving poetic style and thematic concerns.
