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.
Only 36 plays of Shakespeare were published in the 'First Folio' in 1623, where 4 plays, Cardenio', 'Love's Labour's Won', 'Pericles, Prince of Tyre', and 'The Two Noble Kinsmen' were excluded.
