"Abridged" betyder helt enkelt att boken kortats ner. Eller som i Tiger inbyggda ordboken Dictionary definierar begreppet:
abridge |??br?d?| verb [ trans. ] (usu. be abridged)
1 shorten (a book, movie, speech, or other text) without losing the sense : the cassettes have been abridged from the original stories | [as adj.] ( abridged) an abridged text of his speech.
