The Thing on the Doorstep and Other Weird Stories is Penguin Classics' second omnibus edition of works by 20th-century American author H. P. Lovecraft. It was released in October 2001 and is still in print.
This edition is the second in Penguin Classics' series of paperback collections. Again, it collects a number of Lovecraft's most popular stories in their latest "definitive" editions as edited by S. T. Joshi. Many of the texts are the same as those from the earlier Arkham House hardcover editions, with the exception of At the Mountains of Madness, which has recently been released in a definitive edition by the Modern Library, with an introduction by China Miéville and also including Lovecraft's essay on the history and evolution of weird fiction, Supernatural Horror in Literature.
All of the stories collected in this edition can also be found at Wikisource. Scholars should note that the texts transcribed on Wikisource may contain errors, or may represent "uncorrected" versions.
