Hey all, I've been working to get rid of all of my physical books to the point where 90% of new books I buy are e-books so that I'm not harming the earth. However, one scary thought crept into my mind: What if the e-books I'm reading have been manipulated and their content is wrong? I find this extremely worrying to the point where I haven't been able to sleep.

An example of what I mean: I think I'm reading an e-book written by Arnold Schwarzenegger on weight training that promises to give the best results, but I'm actually reading an e-book that contains information that could harm me and is just an e-book written by someone wanting to be mischievous. Or an e-book written by Karl Marx about a criticism of socialism, when in fact a person has manipulated the e-book into a positive view on capitalism. I think I've received information from Karl Marx, but it's a completely altered e-book.

I know if I buy an e-book from Amazon it's most likely genuine, but the vast majority of the e-books I'm reading are from people who have just written their own e-books and released it online without a publisher at all. Many are free e-books. A lot of the e-books I'm reading now are educational so I want to know that what I'm reading is genuine.

A physical book is much harder for someone to make alterations it. It doesn't seem hard for someone to make alterations to an e-book and so the e-book is now 'tainted'.

Is there a way I can check that the e-books I'm reading are genuine?

How can I trust that an e-book hasn't been manipulated?

I'd appreciate any help to calm my mind!
