From Chapter 69 of the Decline & Fall

The coronation of the German emperors at Rome, more especially in the xith century, is best represented from the original monuments by Muratori (Antiquitat. Italiae Medii Aevi, tom. i. dissertat. ii. p. 99, etc). and Cenni, (Monument. Domin. Pontif. tom. ii. diss. vi. p. 261), the latter of whom I only know from the copious extract of Schmidt (Hist. des Allemands tom. iii. p. 255 - 266).
