Terry Pratchett - The Science of Discworld II - The Globe

The Librarian looked a little uncertain at that. Rincewind knew why. It was hard to be an orangutan in Unseen University, and the only way the Librarian had been able to deal with it was by acknowledging Mustrum Ridcully as the alpha male, even though the Archchancellor seldom climbed up to a high place on the rooftops and called mournfully over the city at dawn. This meant that, unlike the other wizards, he found it very hard to shrug off an archchancelloric command. It was a direct, fang-revealing, chest-beating challenge. Rincewind had an idea.

'If we put the globe in the Library,' he said to the ape, 'then that would mean that even though you are travelling in L-space you would not be taking Mr. Stibbons anywhere outside the Library. I mean, the globe would be inside the library, so even though you'd wind up in the globe, you really wouldn't have travelled very far at all. A few feet, maybe. The globe's only infinite on the inside, after all.'

'Well, Rincewind, I am impressed,' said Ponder, while the Librarian looked perplexed. 'I'd always thought of you as rather stupid, but that was a remarkable piece of verbal reasoning. If we put the globe down right on the Librarian's desk, say, then the whole journey would take place inside the library, right?'

'Exactly,' said Rincewind, who was prepared to overlook 'rather stupid' in view of this unexpected praise.

And it's perfectly safe in the library, after all ...'

'Big thick walls. Very safe place,' Rincewind agreed.

'So, put like that, no harm will come to us,' said Ponder.

'There you go with the "us" again,' said Rincewind, backing away.

'We'll find them and bring them back!' said Ponder. 'How hard can it be?'

'It can be incredibly hard! There's elves there! You know elves! They are dangerous! Drop your guard for a moment and they can control your mind!'

'They chased me through some woods once,' said Ponder. 'They are very frightening. I remember writing that down in my diary.'

'You wrote down in your diary that you were scared?'

Yes. Why not? Don't you?'

'I haven't got a big enough diary. But it makes no sense! There's nothing on the Roundworld that elves would be interested in! They like to have ... slaves. And we've never seen anything evolve that's bright enough to be a slave.'

'You might have missed something,' said Ponder.

'No, I say you, you say we,' said Rincewind.

They both stared at the globe.

'Look, it's like having a pot plant,' said Ponder. 'If it has greenfly, you try to squash them.'

'I never do that,' said Rincewind. 'Greenfly may be small, but there's a lot of them ...'

'It was a metaphor, Rincewind,' said Ponder, wearily.

'... I mean, supposing they decide to gang up?'

'Rincewind, you are the only other person here who knows anything at all about Roundworld.

You will come with us or ... or ... I'll tell the Archchancellor about the seven buckets.'

'How do you know about the seven buckets?'

'And I'll explain to him how all of your jobs could easily be done by a simple set of instructions for Hex, too. It'd take me about, oh, thirty seconds. Let's see ...

Or possibly RUN RINCEWIND'

'You wouldn't do that!' said Rincewind. 'Would you?'

'Certainly. Now, are you coming? Oh, and bring the Luggage.'

Knowledge = power = energy = matter = mass, and on that simple equation rests the whole of L- space. It is via L-space that all books are connected (quoting the ones before them, and influencing the ones that come after). But there is no time in L-space. Nor is there, strictly speaking, any space. Nevertheless, L-space is infinitely large and connects all libraries, everywhere and everywhen. It's never further than the other side of the bookshelf, yet only the most senior and respected librarians know the way in.

From inside, L-space looked to Rincewind like a library designed by someone who did not have to worry about time, budget, strength of materials or physics. There are some laws, though, that are coded into the very nature of the universe, and one is: There Is Never Enough Shelf Space [11] Others found by research wizards include Objects In The Rear View Mirror Are Closer Than They Appear, No User Serviceable Parts Inside and, of course May Contain Nuts. .

He turned and looked back. They'd entered L-space by walking through what had looked like a solid wall of books. He knew it was a solid wall, he'd taken books off those shelves before now.

You had to be a very senior Librarian indeed to know in what precise circumstances you could step straight through it.

He could still see the library through the gap, but it faded from view as he watched. What remained was books. Mountains of books. Hills and valleys of books. Perilous precipices of books. Even in what passed for the sky, which was a sort of blue grey, there was a distant suggestion of books. There is never enough shelf space, anywhere.

Ponder was carrying a considerable amount of magical equipment. Rincewind, being a more experienced traveller, was carrying as little weight as possible. Everything else was being carried by the Luggage, which looked like a sea chest but with a number of pink, human-like and fully operational feet.

'Under the rules of the Roundworld, magic can't work,' said Ponder, as they followed the Librarian. 'Won't the Luggage stop existing?'

'It's worth a try,' said Rincewind, who felt that owning a semi-sapient and occasionally homicidal box on legs reduced his opportunities to make live friends, 'but it doesn't usually worry about rules. They bend round it. Anyway, it's already been there before, for a very long time, without any damage. To the Luggage, anyway.'

The walls of books shifted as the wizards approached; in fact, each step radically changed the nature of the bookscape which was in any case, said Ponder, a mere metaphorical depiction created by their brains to allow them to deal with the unimaginable reality. The shifting perspective would have given most people a serious headache at least, but Unseen University had rooms where the gravity moved around during the course of a day, one corridor of infinite length and several windows that only existed on one side of their walls. Life at UU reduced your capacity for surprise by quite a lot.

Occasionally the Librarian would stop, and sniff at the books nearest to him. At last he said 'ook', quietly, and pointed to another stack of books. There were, drawn gently on the spine of an old leather-bound volume, some chalk marks.

'Librarian-sign,' said Rincewind. 'He's been here before. We're close to Roundworld book-space.'

'How could he—' Ponder began, and then said: 'Oh. I see. Er ... Roundworld exists in L-space even before we created it? I mean yes, obviously I know that's true, but even so—'

Rincewind took a book from a pile near him. The cover was brightly coloured and made of paper, suggesting an absence of cows on the originating world, and had the title: Sleep Well My Lovely Falcon. The words inside made even less sense.

'It might not have been worth our trouble,' he said.

The Librarian said 'ook', which Rincewind understood as 'I'm going to get into real trouble with the Secret Masters of the Library for this day's work'.

Then the ape appeared to triangulate on the bookscape around him and knuckled forward, and vanished.

Ponder looked at Rincewind. 'Did you see how he did that?' he said and then a hairy red arm appeared out of the air and jerked him off his feet. A moment later the same thing happened to Rincewind.

It wasn't much of a library, but Rincewind knew how this worked. Two books were a library - for a lot of people, two books were an enormous library. But even one book could be a library, if it was a book that made a big enough dimple in L-space. A book with a title like 100 Ways with Broccoli was unlikely to be one such, whereas A Relationship Between Capital and labour might be, especially if it has an appendix on making explosives. The deeply magical and interminably ancient volumes in the Library of UU strained the fabric L-space like a baby elephant on a worn- out trampoline, leaving it so thin that the Library was a potent and easy portal.
