Robin Williams' life story is to be told in a biography penned by a New York Times culture reporter.
Dave Itzkoff has written extensively about the late actor-comedian, who was found dead in his California home aged 63 earlier this month.
The as-yet-untitled book has not been given a release date but will be published by Henry Holt and Co.
"Robin Williams was a cultural hero of mine, and in the encounters and interactions I was able to share with him, he was always gentle and generous, humane and thoughtful and hilarious," Itzkoff said in a press release.
Past work from Itzkoff includes a 2009 profile piece on the Oscar-winning Good Will Hunting star shortly after he underwent heart surgery following a period of alcohol abuse.

Video: Robin Williams' career
Williams was honoured at both the MTV Video Music Awards and the Emmys last weekend, but both tributes were met with controversy.
The former remembered Williams through a 20-second slide show featuring random images of the star, which many criticised for "insulting" lack of effort.
Billy Crystal led the similarly "offensive" Emmys memorial attempt, which included a short snippet of a stand-up performance showing Williams borrowing a pink scarf from an audience member and wrapping it around his head like a hijab.
