Although
Mionnet made a lot of corrections to
his own copies, only one edition of most of
his volumes was published.
An exception is Volume 1 of which there were two editions, 1806 and 1822.
And until
RPC a) includes the Severans and
b) use permanent reference numbers instead of "temporary" numbers which are likely to change in the future,
Mionnet will continue to be a go-to source.
