Wow, the British Library has posted 93 copies of 21 of Shakespeare’s plays in their original quarto format online for our fun and delectation. A fabulous resource.

‘None of Shakespeare’s manuscripts survive, so the printed texts of his plays are our only source for what he originally wrote. The quarto editions are the texts closest to Shakespeare’s time. Some are thought to preserve either his working drafts (his foul papers) or his fair copies.’
