Card, Orson Scott. Wyrms (New York: TOR, 1988) 345 p.

On a planet where all the Wise people have been called away and enslaved, a small creature of the race of dwelfs gathers knowledge. Her name is Heffiji. She has a very small brain and cannot retain a thought for more than a few seconds, but she devises a system of writing things down and storing the papers where she knows she can find them later. Heffiji is short for Mikias Mikuam Heffiji Ismar which means Never to Lose the finding place. "That’s me, said Heffiji. I don't know anything but I can find everything." (p. 180).

Heffiji's house is in fact a great library. It is here the heroine of the story gains the information she needs to complete her quest. Heffiji's house finally becomes the center of a great university.
