The implementation of a second edition was last updated in 1933 for publication in Berlin. The first booklet of the second edition was led by
Edmund Groag and
Arthur Stein The index of names and people integral to the
PIR was in the meantime made searchable on the website of the
PIR. Volume 2 of the
PIR includes notes for all the well-known
Roman senators, the
nobles, and some civil servants not of equestrian rank, such as
manumitted imperial freedmen who are attested in the literary tradition. Entries in the
PIR are indexed by the initial letter of the name, then by the number of the entry, e.g.
Tiberius Claudius Pompeianus is cited as
PIR2 C 973 (the 973rd entry under the letter C). == See also ==
