A rare copy of the first collected edition of plays by British playwright William Shakespeare, has been discovered in a stately home on a Scottish Island. The First Folio published in 1623, contains copies of some of the playwright's best-known plays, and is thought to be one of most sought-after books in the world. There are known to be around 230 copies of the folio, which contains 36 plays and was written seven years after his death. One copy of the folio was sold for nearly AED18 million in 2003.
