I'm sorry, this is a missunderstanding.
I was talking about scientific documents that already come with a MD5 Hash. I gave some examples
here (in german).
When you talk to a scientist you'd like to make sure that you both have exactly the same document, or you'd like to know if you have exactly this specific document from this specific source. And the easiest way for that would be a comparison of the MD5 Hash. That's why the University of Freiburg publishes them.
It's easy to manipulate a document; or you can have different versions of a document, three different scanns of three different print copies of the same book, for example.
It's possible to manipulate electronic books, actually it's very easy. A kid could do it just for fun. That's why I'd like to see the MD5 Hash of my document in a scientific reader.
