In the Book Review 'Amphibian mystery misread' by Alan Pounds and Karen Masters (Nature 462, 38–39; 2009) the sentence “Collins and Crump's selection of published work and quoted opinions downplays such links” should have read “Collins and Crump's assessment of published work and the opinions that they quote downplay such links.”

In Alison Abbott's Arts Review 'Florence's observatory restored' (Nature 462, 40; 2009), “Pietro Leopardo” should have read “Pietro Leopoldo”.
