Frankenstein fans were invited to Oxford University's Bodleian Library to see the original manuscripts and celebrate a new book.

Library curators organised a special Frankenstein Day today to mark the publication of The Original Frankenstein, a ground-breaking new look at the first work of science fiction.

Prof Charles E Robinson has used the handwritten draft from 1816-1817, held at the library, to distinguish author Mary Shelley’s words from the additions of her husband, the poet Percy Shelley.

Prof Robinson flew in from the University of Delaware in the US to give a lecture.

Samuel Fanous, pictured, head of communications and publishing at the Bodleian, said: "Up until now, we have not been able to read Frankenstein without Percy's accretions, but readers can now go back to what Mary originally wrote.”
