The Minas Tirith Archives Department probably had strict rules about proper record keeping procedures too, but try telling Gandalf anything and you’d probably get some form of “I do what I want.”
Eh, I’m gonna quibble with “the Minas Tirith Archives Department probably has strict rules about proper record keeping procedures”, given that we see Gandalf being shown into a poorly lit room full of jumbled stacks of books and loose papers that was clearly a disaster before he arrived. Maybe they did have good standards at one point, but Denethor cut the library budget and they had to downsize their storage space, let go of some staff, you know how it is.
