I would like to create a custom field (or modify an existing field that is currently blank, such as “call number”) and populate this field with numbers 1-655, while the references are sorted alphabetically by Author’s last name.
so author Alan Aardvark would be assigned #1 in the custom field … up through Zip Zazz #655.
I haven’t found a way to insert a formula (n+1) in the change/move/copy Fields box.
not without exporting the library and reimporting it as a new library (which is also not easy). Why does it need to be hardwired in this way in the library? – But Tim’s suggestion is even better!
