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.
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.
