Unfortunately the Balfour Library does not own a copy of John James Audubon's magnificent, 1m tall Birds of America, with 435 hand-painted plates illustrating American birds in their natural habitats, so you may be interested in the iPad or eBook version of a copy owned by the Natural History Museum (NHM).
A resized print edition of the work will also be launched by the NHM.
The NHM's art collection holds half a million artworks, representing all the great natural history
artists. There are also over 1 million books, including some richly illustrated volumes of great historical significance.
