Excerpts from the diaries of late Nirvana frontman Kurt Cobain have been published in the latest issue of US magazine Newsweek and UK newspaper The Observer.

The excerpts are part of a new book called 'Journals', which also includes letters, drawings and lyrics by the singer.

'Journals' is published in November and is preceded by the release next week of a Nirvana compilation album.

Among the tracks on the album is the legendary unreleased song 'You Know You're Right'.
