It is both, E-books are fine as long as they aren't all E-books, because what happens when the systems crash, power failure so on and so forth.... or
someone just decides to delete them.... sure forensically you can recover it, but that's a SOB to do... IMO Hard Copies are a MUST also, a good
hacker can re-write a PDF so I mean, would you really want to trust getting your information from an E-book, unless it was a completely secure
terminal, with very restrictive user privelidges.....
