All 38 plays which we recognize as Shakespeare's were published before 1634 in some form. We are very fortunate in that two friends of Shakespeare's, Heminges and Condell, decided after his death to publish a compendium of his plays.
William Shakespeare's plays were published in 1623, about seven years after Shakespeare's death, in a volume entitled Mr William Shakespeares Comedies, Histories & Tragedies, known as The First Folio, containing the text of 36 plays.he truth is that some of Shakespeare's plays may have never even been written down, and some that were written down may have been destroyed by the passage of time and the elements. At least two plays whose titles we know have disappeared completely. There may be others of which we do not even know the title.
