Fermat's claim, written around 1637, of a proof of Fermat's last theorem too big to fit in the margin is the most famous mathematical marginal note. Voltaire, in the 1700s, annotated books in his library so extensively that his annotations have been collected and published. The first recorded use of the word "marginalia" is in 1819 in "Blackwood's Magazine". From 1845 to 1849 Edgar Allan Poe titled some of his reflections and fragmentary material "Marginalia." Five volumes of Samuel T. Coleridge's marginalia have been published. Beginning in the 1990s, attempts have been made to design and market e-book devices permitting a limited form of marginalia.
