Bede also had correspondents who supplied him with material. Albinus, the abbot of the monastery in Canterbury, provided much information about the church in Kent, and with the assistance of Nothhelm, at that time a priest in London, obtained copies of Gregory the Great's correspondence from Rome relating to Augustine's mission. Almost all of Bede's information regarding Augustine is taken from these letters. Bede acknowledged his correspondents in the preface to the "Historia Ecclesiastica"; he was in contact with Bishop Daniel of Winchester, for information about the history of the church in Wessex and also wrote to the monastery at Lastingham for information about Cedd and Chad. Bede also mentions an Abbot Esi as a source for the affairs of the East Anglian church, and Bishop Cynibert for information about Lindsey.
