In 1944, when he was 22, Jack Kerouac lost a manuscript — in a taxi, as he thought, but probably in Allen Ginsberg’s room at Columbia University — and it stayed lost until 2002, when it was auctioned at Sotheby’s. Now it has been published, all 70 pages of it, together with some youthful sketches and some letters between Kerouac and his father, in an edition by a professor at Lowell, Massachusetts, Kerouac’s home town.
