I would try to make a list of all newspapers and magazines where Christopher Hitchens wrote at least one article. Interview does not count.
Vanity Fair (First article published in 1992, but mostly 2006-2011)
The Atlantic (2001-2011)
New Statesman (joined in 1973)
The Nation (Mostly 1982-2002)
London Review of Books (1983-2002)
The Times Literary Supplement (started writing for the TLS in 1970)
