I am pretty sure the online database has all the
seals that are published in parts 1-6 available. But the
collection is far greater, and they are
still acquiring new pieces, so new pieces keep being added.
I think flipping through pages is not time-effective if you are not looking for anything specific. So if you read 'MAKEDONON', it definitely pays flipping through the Macedon pages. Also note that DO parts 1-5 only have
seals with geographic references. If your seal only has a name, or name and office, it's not in there.
DO
Part 6 is devoted to imperial and patriarchal
seals.
Part 7 to anonymous
seals with iconographic imagery on both sides. Both are primary references for that
type of seal.
