A Journal of Impossible Things (Human Nature)

The Journal of Impossible Things was a journal kept by John Smith of his strange dreams - actually memories from his life as the Doctor's tenth incarnation, with some memories of previous incarnations' appearances. All but Martha Jones believed these to be products of John Smith's imagination.

After John Smith
John Smith gave the book to Joan Redfern, who apparently annotated it with a detailed chronicle of her love story with a strange visitor from beyond the stars. In the 21st century, this annotated version of the book fell in possession of her great grand daughter, Verity Newman, who published it, again titled Journal of Impossible Things as a partial biography of Joan herself. The Doctor, slowly dying from radiation sickness, attended a book signing by Newman, giving away his identity by naming himself as "The Doctor" (Verity recognized the name used by John Smith). He then asked Verity about Joan, going away to meet his final fate after being assured of Joan's ultimate happiness in life. (DW: The End of Time, Part Two)

Behind the scenes
An actual, intricately-illustrated prop book was created for the filming. Later, Character Options, which held some of the rights to release toys and merchandise based upon the series, issued a faux leather-bound reproduction of the book.
