2000 Year Diary
From Tardis Wiki, the free Doctor Who reference
The Two Thousand Year Diary was a journal kept by the Twelfth Doctor. It was an updated version of his Nine Hundred Year Diary, which was, in turn, a continuation of his Five Hundred Year Diary. The Doctor used the Two Thousand Year Diary to remind himself of the Mire when they threatened a Viking village. (TV: The Girl Who Died)
