Time log

The Doctor kept time logs, at least in two volumes.

The Fourth Doctor hinted he was too busy to still keep track of his travels. However, he asked Adric to search the logs for references to previous travels to Traken. Adric managed to read the language of the journal, even if he was hindered by the Doctor's handwriting and by the lack of chronological and logical order ("I read about something that's just happened. The next page says it didn't happen at all!") (TV: The Keeper of Traken)

By the final time of his fifth incarnation, the Doctor confessed to Peri Brown he tried keeping a diary, not chronological, but "the trouble with time travel is one never seems to find the time". (TV: The Caves of Androzani)


 * It is disputable the relationship between these logs and the Five Hundred Year Diary.
