Abridgement

An abridgement (or abridgment) is a condensing or reduction of a book or other creative work into a shorter form while maintaining the unity of the source. The abridgement can be true to the original work in terms of mood and tone, capturing the parts the abridging author perceives to be most important; it could be a complete parody of the original; or it could fall anywhere in-between, either generally capturing the tone and message of the original author but falling short in some manner, or subtly twisting his words and message to favor a different interpretation or agenda. Compare/contrast with epitome.
