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.
Eighteen of Shakespeare's plays exist in one or more quarto versions. The other way the plays have come down to us is what is called the First Folio (published in 1623). After Shakespeare's death in 1616, two of Shakespeare's fellow actors printed 36 of the 38 plays attributed to the Bard in a large book.Some plays (such as The Winter's Tale) only exist in the First Folio.Others, like Hamlet or King Lear, exist in both the First Folio and in one or more quarto versions. Sometimes the differences between the versions are relatively minor and sometimes they are very significant.ome plays (such as The Winter's Tale) only exist in the First Folio.
