Z39.50 Extended Services / Item Order

Dear all,

I am a Librarian and currently work at an organization that develops a software based on Z39.50 Protocol. Trying to interpret the Item Order Extended Service in order to incorporate this particular function in our Z-client, we have a difficulty in understanding the meaning of two specific parameters.

The first is about the values "Private Known" & "Private Not Known" found at Payment Method. The second is about the values "Unfilled Copyright" & "Filled Copyright" found at Auxiliary Status.

Your lights on the particular topics would be very helpful.

Thank you in advance.
