published. A few months after his death, a collection of writings spanning his entire career, Word Virus, was published (according to the book's introduction, Burroughs himself approved its contents prior to his death). Aside from numerous previously released pieces, Word Virus also included what was promoted as one of the few surviving fragments of And the Hippos Were Boiled in Their Tanks, a novel by Burroughs and Kerouac. The complete Kerouac/Burroughs manuscript And the Hippos Were Boiled in Their Tanks was published for the first time in November 2008. A collection of journal entries written during the final months of Burroughs' life was published as the book Last Words in 2000. Publication of a memoir by Burroughs entitled Evil River by Viking Press has been delayed several times; after initially being announced for a 2005 release, online booksellers indicated a 2007 release, complete with an ISBN (), but it remains unpublished. New enlarged or unexpurgated editions of numerous texts have been published in recent years as "Restored Text" or "Redux" editions all containing additional material and essays on the works or incorporating material edited out of previous versions. Beginning with Barry Miles and James Grauerholz' 2003 edition of Naked Lunch, followed by Oliver Harris reconstructions of three trilogies of writings. The first of these are the early writings Junky:the definitive text of "Junk" (2003), Queer: 25th-Anniversary Edition (2010) and The Yage Letters Redux (2006). Following the publication of the latter in December 2007, Ohio State University Press released Everything Lost: The Latin American Journals of William S. Burroughs also edited by Harris, the book contains transcriptions of journal entries made by Burroughs during the time of composing Queer and The Yage Letters, with cover art and review information. There followed "restored text" versions of some of Burroughs' best known novels The Soft Machine, The Ticket that Exploded and Nova Express (styled "the Cut Up Trilogy" officially here for the first time) from Penguin in 2014, and of Burroughs' more obscure collaborative poetic experiments of 1960 Minutes to Go: Redux & The Exterminator: Redux by Moloko Press in 2020. These books, originally pamphlets, are bulked out to three times their original size and the "trilogy" is complete with the completely new BATTLE INSTRUCTIONS an allied experimental collaboration, composited from unpublished drafts and recordings of the same period. Literary style and periods Burroughs' major works can be divided into four different periods.
