Note 009
After his accession he gave orders that ten copies of the
historian should be annually transcribed and placed in the
public libraries. The Roman libraries have long since
perished, and the most valuable part of Tacitus was
preserved in a single MS., and discovered in a monastery of
Westphalia. See Bayle, Dictionnaire, Art. Tacite, and
Lipsius ad Annal. ii. 9.
