When a book becomes influential enough, someone might try to impersonate it, since publishing doesn’t follow any hard rules.
For example, I was explaining to someone that, after (surprisingly not before) I got a job at my local library, I took out a communist manifesto, which I later learned was a fake, with writings in there that were not consistent with the official communist manifesto, such as a call for free love.
I have also spotted a lot of fake versions of Mark Twain books come in, which has a lot of parts deleted or inserted based on the writer’s desire.
On the other side of the issue, lately I’ve been watching a lot of the events unfold in the middle East and have wondered why nobody just ends violence over there for good by making fake Qurans. One or two people have hinted they’ve tried, with some altered movements centered around it (would you call this government gnosticism), but it’s not something you always hear.
What’s the most severe example of a fake version of a book you’ve ever seen/encountered?
I didn’t read or see it, but shortly before one of the Harry Potter books (maybe the 5th) was officially released, someone “leaked a pirated copy” online. Lots of people downloaded it and liked it and weren’t suspicious about it. It advanced the plot in a convincing way, and so on. But it was completely fake, written from scratch by a fan of the series. Ha.
This happened with my friend group and Deathly Hallows. We all read a fake leaked copy before the book came out and made our own personal injokes, like how insane it would be if Harry broke into the Bank and just started flinging Unforgivable Curses at random goblins, or if ANYTHING bad happened to us we’d say *Oh no, Dobby!" and someone would follow up with “We spend two full chapters mourning Dobby.”
it was not a fake leak
I once found a fake Harry Potter book named Harry Potter and Deatbly Hallows, probably just a pirated version of the actual book, never read it, but funny to not spell-check the name.
