It is sometimes recommended that such degrees be listed in one's CV as an award, and not in the education section. With regard to the use of this honorific, the policies of institutions of higher education generally ask that recipients "refrain from adopting the misleading title" and that a recipient of an honorary doctorate should restrict the use of the title "Dr" before their name to any engagement with the institution of higher education in question and not within the broader community. Rev. Theodore Hesburgh held the record for most honorary degrees, having been awarded 150 during his lifetime.
The practice dates back to the Middle Ages, when for various reasons a university might be persuaded, or otherwise see fit, to grant exemption from some or all of the usual statutory requirements for the awarding of a degree. The earliest honorary degree on record was awarded to Lionel Woodville in the late 1470s by the University of Oxford. He later became Bishop of Salisbury.
In the latter part of the 16th century, the granting of honorary degrees became quite common, especially on the occasion of royal visits to Oxford or Cambridge. On the visit of James I to Oxford in 1605, for example, forty-three members of his retinue (fifteen of whom were earls or barons) received the degree of Master of Arts, and the Register of Convocation explicitly states that these were full degrees, carrying the usual privileges (such as voting rights in Convocation and Congregation).
