Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that copyright duration for works published before 1928 is expired?

Yes. A Wikipedia reference states that all copyrightable works published in the United States before 1931, except sound recordings, are in the public domain, which covers works published before 1928. A Wikibooks reference gives pre-1978 duration rules but does not directly address pre-1928 expiry.
