Thanks for the reply.

Continuing with the example mentioned in my post on May 10:

There were 27 Facts linked to the first Source Citation (Ohio 1860 Census - Mercer County Center Township Page 317).

There were 19 Facts linked to the second Source Citation (Ohio 1860 Census - Mercer County Cneter Township Page 317).

After I fixed the typo in the second Source Citaion the same 27 Facts are still linked to the First Source Citation and the same 17 Facts are still linked to the second (now corrected) Source Citation even thought the two Citations are now identical.

No Facts are repeated and no Facts got updated. All I fixed was the typo in the second Citation. All Facts stayed linked to the same Citations even though now the Citations are the same.

Hope this is clearer.

Thanks for the help
