Heinlein's surgical treatment re-energized him, and he wrote five novels from 1980 until he died in his sleep from emphysema and heart failure on May 8, 1988. At that time, he had been putting together the early notes for another World as Myth novel. Several of his other works have been published posthumously. Based on an outline and notes created by Heinlein in 1955, Spider Robinson wrote the novel Variable Star. Heinlein's posthumously published nonfiction includes a selection of correspondence and notes edited into a somewhat autobiographical examination of his career, published in 1989 under the title Grumbles from the Grave by his wife, Virginia; his book on practical politics written in 1946 published as Take Back Your Government; and a travelogue of their first around-the-world tour in 1954, Tramp Royale. The novels Podkayne of Mars and Red Planet, which were edited against his wishes in their original release, have been reissued in restored editions. Stranger In a Strange Land was originally published in a shorter form, but both the long and short versions are now simultaneously available in print. Heinlein's archive is housed by the Special Collections department of McHenry Library at the University of California at Santa Cruz. The collection includes manuscript drafts, correspondence, photographs and artifacts. A substantial portion of the archive has been digitized and it is available online through the Robert A. and Virginia Heinlein Archives.
