If you thought you knew everything there is to know about Jim Morrison, then you’re in for a surprise.

A collection of writings by the late Doors frontman, including previously unpublished material, is slated for release June 8 by the publisher, HarperCollins, paying homage to the musician a few weeks before the 50th anniversary of his death.

‘The Collected Works of Jim Morrison: Poetry, Journals, Transcripts and Lyrics’ is a 600-page tome largely comprising previously published material, including poetry and song lyrics, as well as the posthumously published writing collections, ‘Wilderness’ and ‘The American Night’, in their entirety.

Still, fans of the singer will also be able to discover previously unseen material, including unrecorded song lyrics and handwritten excerpts from no less than 28 recently discovered notebooks.

One such notebook, which Jim Morrison is said to have penned in Paris shortly bore his death, July 3, 1971, is even reproduced in full size for inclusion in ‘The Collected Works of Jim Morrison: Poetry, Journals, Transcripts and Lyrics’.

“Jim Morrison is an enduring, influential force in the world of entertainment as well as one of the most notable poets of his generation.

‘The Collected Works of Jim Morrison’ is a highly curated anthology of his prodigious creative output. This is an exceptional collection we’re thrilled and honored to publish in conjunction with Jim’s family, Jennifer Gates at Aevitas, and the incredible support of JAM, Inc., the estate’s manager, who gave us unprecedented access to the Morrison archives,” said executive editor, Elizabeth Sullivan in a statement.

The book release will be accompanied by an audiobook featuring Jim Morrison’s last poetry recording session at the Village Recorder on his 27th birthday in 1970.
