The World was a daily newspaper published in New York City in the 20th century.
In an alternate timeline accidentally created when Leonard McCoy saved the life of Edith Keeler, he'd noticed several New York City newspapers, including The New York Times, The World and The Star Dispatch. When he told her that his friends might have trouble locating him, Keeler suggested that he buy classified ads in local newspapers. He placed ads in all of the local papers in hopes that computer records of some might survive into the 23rd century. (TOS - Crucible novel: Provenance of Shadows)
