This quote is from the FT IT section, November 2003:

‘Industry experts point out that often a large percentage, sometimes the majority, of information stored is duplicated or out of date information’

And to that could be added triplicate and beyond, inaccurate, incomprehensible to anyone else, impossible to find.

Imagine if there were duplicate or out of date libraries ? or duplicate and out-of-date staff? How quickly would they last?
