This page should be rewritten to focus directly on the times the 500 year diary has appeared, not document the full contents of the Doctor's entries which would be better suited to the Doctor's diaries and pages such as Eleventh Doctor's diary. Besides, the Doctor isnt the only person in the DWU who have used 500 year diaries.
These problems might be so great that the article's factual accuracy has been compromised. Talk about it here or check the revision history or Manual of Style for more information.

Behind the scenes[[edit] | [edit source]]
Information from invalid sources[[edit] | [edit source]]
Information recorded in the Doctor's Five Hundred Year Diary concerning The Doomsday Contract stated that there was once a man, John Lloyd, who worked with Douglas Adams on The Hitchhiker's Guide to the Galaxy. Not long after, Douglas became a script editor on Doctor Who, which prompted Lloyd to submit a story treatment entitled The Doomsday Contract. Lloyd toiled over many redrafts of the script, but it fell through and never made it to television.
43 years later, the "remarkable" company Big Finish adapted The Doomsday Weapon into a "full cast audio version". It was a massive success. (WC: Tom Baker stars in John Lloyd's lost Doctor Who adventure, The Doomsday Contract)
