Marienbad My Love is made of cuts from other books, but some of them were by the same author.
Straight from the horse's mouth at the website of the book and author:
This multi-million-word, multi-volume work has been meticulously assembled through calculation and chance from fragments of pre-existing texts both written and appropriated by Mark Leach over the course of 30 years - "the movie," as Leach calls it, "of all my labors and all my inspirations."
As the author said:
hard, but it’s not always easy to be a scissors-and-paste man, either.
He's also willing to give as well as take: he's lifted copyright protections on Marienbad My Love and invited any other budding writers to plagiarise from it. I'm not sure what this says about him, but he's also gleefully copied on his website the speculations from internet forumgoers that he's mentally ill. Furthermore:
By no means does Leach believe his record will stand unchallenged. He is
hedging his bet by also challenging the records for:
- longest word. Also
called "the holy Jah," the 4.4-million-letter noun is a coinage of words from
the world's faiths and means "god within."
- longest sentence (3 million
- longest book title (6,700 words)..
