Seldon said, "You know what you make it sound like? It would appear-"
Dors said, "I'll tell you how it appears. All this talk of sex makes one thing clear to me. I'm simply not going to let you out of my sight anymore."
"What?"
"Twice I let you go, the first time through my own misjudgment and the second because you bullied me into it. Both times it was clearly a mistake. You know what happened to you the first time."
Seldon said indignantly, "Yes, but nothing happened to me the second time."
"You nearly got into a lot of trouble. Suppose you had been caught indulging in sexual escapades with a Sister?"
"It wasn't a sexual-"
"You yourself said she was in a high state of sexual excitement."
"But-"
"It was wrong. Please get it through your head, Hari. From now on, you go nowhere without me."
"Look," said Seldon freezingly, "my object was to find out about Mycogenian history and as a result of the so-called sexual escapade with a Sister, I have a book-the Book."
"The Book! True, there's the Book. Let's see it."
Seldon produced it and Dors thoughtfully hefted it.
She said, "It might not do us any good, Hari. This doesn't look as though it will fit any projector I've ever encountered. That means you'll have to get a Mycogenian projector and they'll want to know why you want it. They'll then find out you have this Book and they'll take it away from you."
Seldon smiled. "If your assumptions were correct, Dors, your conclusions would be inescapable, but it happens that this is not the kind of book you think it is. It's not meant to be projected. The material is printed on various pages and the pages are turned. Raindrop Forty-Three explained that much to me."
"A print-book!" It was hard to tell whether Dors was shocked or amused. "That's from the Stone Age."
"It's certainly pre-Empire," said Seldon, "but not entirely so. Have you ever seen a print-book?"
"Considering that I'm a historian? Of course, Hari."
"Ah, but like this one?"
He handed over the Book and Dors, smiling, opened it-then turned to another page-then flipped the pages. "Its blank," she said.
"It appears to be blank. The Mycogenians are stubbornly primitivistic, but not entirely so. They will keep to the essence of the primitive, but have no objection to using modern technology to modify it for convenience's sake. Who knows?"
"Maybe so, Hari, but I don't understand what you're saying."
"The pages aren't blank, they're covered with microprint. Here, give it back. If I press this little nubbin on the inner edge of the cover- Look!"
The page to which the book lay open was suddenly covered with lines of print that rolled slowly upward.
Seldon said, "You can adjust the rate of upward movement to match your reading speed by slightly twisting the nubbin one way or the other. When the lines of print reach their upward limit when you reach the bottom line, that is-they snap downward and turn off. You turn to the next page and continue."
"Where does the energy come from that does all this?"
"It has an enclosed microfusion battery that lasts the life of the book."
"Then when it runs down-"
"You discard the book, which you may be required to do even before it runs down, given wear and tear, and get another copy. You never replace the battery."
Dors took the Book a second time and looked at it from all sides. She said, "I must admit I never heard of a book like this."
"Nor I. The Galaxy, generally, has moved into visual technology so rapidly, it skipped over this possibility."
"This is visual."
"Yes, but not with the orthodox effects. This type of book has its advantages. It holds far more than an ordinary visual book does."
Dors said, "Where's the turn-on?-Ah, let me see if I can work it." She had opened to a page at random and set the lines of print marching upward. Then she said, "I'm afraid this won't do you any good, Hari. It's pre-Galactic. I don't mean the book. I mean the print... the language."
"Can you read it, Dors? As a historian-"
"As a historian, I'm used to dealing with archaic language-but within limits. This is far too ancient for me. I can make out a few words here and there, but not enough to be useful."
"Good," said Seldon. "If it's really ancient, it will be useful."
"Not if you can't read it."
"I can read it," said Seldon. "It's bilingual. You don't suppose that Raindrop Forty-Three can read the ancient script, do you?"
"If she's educated properly, why not?"
"Because I suspect that women in Mycogen are not educated past household duties. Some of the more learned men can read this, but everyone else would need a translation to Galactic." He pushed another nubbin. "And this supplies it."
The lines of print changed to Galactic Standard.
"Delightful," said Dors in admiration.
"We could learn from these Mycogenians, but we don't."
"We haven't known about it."
"I can't believe that. I know about it now. And you know about it. There must be outsiders coming into Mycogen now and then, for commercial or political reasons, or there wouldn't be skincaps so ready for use. So every once in a while someone must have caught a glimpse of this sort of print-book and seen how it works, but it's probably dismissed as something curious but not worth further study, simply because it's Mycogenian."
"But is it worth study?"
