I think I can add something to the discussion. Many jurisdictions gave the
Genealogical Society of Utah permission to copy the microfilm and
distribute copies of the film, as long as patrons agreed not to make copies
of the information for anything other than personal use. If this
restriction was made on a specific film, a statement to the effect in on the
side of the box. This is common on films borrowed from English records,
South Carolina, Alabama, and Georgia.
Some jurisdictions did not even allow the FHC to make copies to be loaned to
the local FHC. Apparently South Carolina once placed this restriction on
any record microfilmed by the Gen. Soc. of Utah. For a while a couple of
mid western states even had this restriction. There are other holdings
which are restricted to use only in Salt Lake and that restriction is listed
on the library card.
In order to stop the misuse of books and other copy writed information on
microfilm, the FHC instituted a policy that discourages people from copying
whole books rather than purchasing them on the open market.
