The Signet Classics Abridged Works are notable examples of abridgment; the Signet Classics Bible, for example, is 40 percent shorter than the 850,000-word King James Version. Although well-known passages in abridged works are often left intact, editors may remove "repetition, rhetoric and redundancy" from a complete work. Until roughly the mid-19th century, the act of abridgment was widely regarded as fair use and was among the most frequently abused loopholes in British
