Hi Dalton,
Sorry to confirm i used the option "Create an empty book", could you have a look on this csv:
https://e-nautia.com/brokengillou/di...ZMI/Mashup.csv
As i select my csv in either auto or manual mode no book list appears to apply further operations on. I expected to get to this first step then trying to assign sudoc number in link to identifiers as sudoc:########### (also isbn).
Thanks,
Gilles
NB: I found this tool relative to SUDOC:
