I was recently asked to add a note to our outgoing borrowing requests so that when libraries got our request, certain information would be on every request.
This is an example of what these extremely common notes might look like in a lending request in ILLiad.
Once I found the correct OCLC service, editing/adding this note was extremely easy. The Borrower Notes and Billing Notes fields are located on the “Borrower Data” tab within OCLC Service Configuration. Currently, the login page is https://worldcat.org/config/ under Worldshare ILL configuration.
