Question about a book (glitch)

[gugnihr]

Near Winterhold I have found something like a shrine with various skeletons. One of those skeletons has a book (the doors of Oblivion), but every single time you check it he has one more copy of that book (he creates books basically, one everytime you check it).
Is it dangerous to take those books?
I mean, is there a chance that those books will cause bugs or glitches if I take them?

I'm pretty sure this is not intentional because it looks rather random and meaningless so I'm sure it is a bug.

This is an old gold making glitch, that body will keep replicating that book as long as you don't read that book. The moment you read the book it will stop producing copies. It's a slow way to make money though, as it is small in value. But it works nonetheless

EDIT: Forgot to answer your questions fully, no there will be no bugs or glitches if you continue to take them.
