Was it an encyclopedia set specifically for children? The first thing that came to mind was the Childcraft books. They’ve been around for a long time but were continually updated and reissued, so there’s a set from the 1990s. My family had a set from the 70s. There was a volume called Once Upon a Time, which had tales in it, and another called Stories and Poems. Other volumes were subjects like How Things Work. All for young readers.
Lots of used full sets are available online if this is it.
