“The three rules of the Librarians of Time and Space are: 1) Silence; 2) Books must be returned no later than the last date shown; and 3) Do not interfere with the nature of causality.”

“Stanley always followed the rules. All sorts of things could go wrong if you didn't. So far he'd done 1:Upon Discovery of the Fire, Remain Calm.Now he'd come to 2: Shout 'Fire!' in a Loud, Clear Voice.'Fire!' he shouted, and then ticked off 2 with his pencil.Next was: 3: Endeavour to Extinguish Fire If Possible.Stanley went to the door and opened it. Flames and smoke billowed in. He stared at them for a moment, shook his head, and shut the door.Paragraph 4 said: If Trapped by Fire, Endeavour to Escape. Do Not Open Doors If Warm. Do Not Use Stairs If Burning. If No Exit Presents Itself Remain Calm and Await a) Rescue or b) Death.”

“Books must be treated with respect, we feel that in our bones, because words have power. Bring enough words together they can bend space and time.”

“The Librarian considered matters for a while. So…a dwarf and a troll. He preferred both species to humans. For one thing, neither of them were great readers. The Librarian was, of course, very much in favor of reading in general, but readers in particular got on his nerves. There was something, well, sacrilegious about the way they kept taking books off the shelves and wearing out the words by reading them. He liked people who loved and respected books, and the best way to do that, in the Librarian’s opinion, was to leave them on the shelves where Nature intended them to be.”

“Along with the standard computer warranty agreement which said that if the machine 1) didn't work, 2) didn't do what the expensive advertisement said, 3) electrocuted the immediate neighbourhood, 4) and in fact failed entirely to be inside the expensive box when you opened it, this was expressly, absolutely, implicitly and in no event the fault or responsibility of the manufacturer, that the purchaser should consider himself lucky to be allowed to give his money to the manufacturer, and that any attempt to treat what had just been paid for as the purchaser's own property would result in the attentions of serious men with menacing briefcases and very thin watches.”

“People flock in, nevertheless, in search of answers to those questions only librarians are considered to be able to answer, such as "Is this the laundry?" "How do you spell surreptitious?" and, on a regular basis, "Do you have a book I remember reading once? It had a red cover and it turned out they were twins.”

“The librarians were mysterious. It was said they could tell what book you needed just by looking at you, and they could take your voice away with a word.”
