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.’
