Ted, The only thing to do is check what LC says at http://www.loc.gov/marc/authority/ad7xx.html (it’s way too complicated to try to describe separately). Our Aleph system is set up to ignore these (and if it wasn’t, I would change it to make it ignore them). HTH. Best wishes, Alan ============================== Mr A.V.

Hello, In the latest batch of name authority updates there are a number of records with a change I don't understand. The new records have a new 700 14 field that is the same as the 100 field. Our III system interprets this 700 as a See also reference. What is the purpose of this field? Examples: n 79141239 100 1 Housman, A. E.|q(Alfred Edward),|d1859-1936 700 1 4 Housman, A. E.|q(Alfred Edward),|d1859-1936 n 50030817 100 1 Hornung, E. W.|q(Ernest William),|d1866-1921 700 1 4 Hornung, E.
