- Chronicle; Deeds of the Kings, Gervase of Canterbury (Chronica about 1188 to 1199; Gesta Regum about 1199 to 1210). The Chronica stops in 1199, so for 1200 the witness is the briefer Gesta Regum, which notes John's peace with Philip, the coronation of Isabella at Westminster on 8 October 1200, and matters touching Canterbury: the archbishop Hubert Walter as chancellor, the cathedral priory's quarrel with him, and the Lambeth college dispute lately settled by the pope.

- English Chronicle of Ralph of Coggeshall, Ralph of Coggeshall (about 1200 to 1224, in stages). Short but independent entries for 1200 from a Cistercian house in Essex: John's levy on the Cistercians and the carucage, the peace with Philip, the king's new marriage and the queen's coronation, and the death of Hugh of Lincoln. Read online
- Flowers of History, Roger of Wendover (about 1220 to 1235 at St Albans). For 1200 Wendover is mostly Howden rewritten, so he is a second witness only where he adds St Albans material: a long account of Hugh of Lincoln's last months, death and funeral, and anecdotes about John's conduct toward the Cistercians and his new queen.
