The first four stories were collected, along with a new story taking place before the others, as a fixup published by Gnome Press in 1951 as Foundation.
Prve su četiri priče sabrane, skupa s novom pričom čija se radnja odvija prije ostalih, u jedan svezak koji je 1951. objavila izdavačka kuća Gnome Press pod naslovom Zaklada.
