It is generally easiest to suggest that the patron contact the holding library directly through a chat or similar link on the institution's website. Using a general portal allows requests to be tracked and directed and is much more efficient than attempting to determine who the appropriate person to contact might be. Also, sometimes materials turn out to have been digitized since they were microfilmed. Before proceeding with a request to create a surrogate of a surrogate, check for high-quality digital images of the original item at the holding library. If you find such images and they are not already linked in the RISM record, email this information to RISM Zentralredaktion so that they may insert a link (Isham staff with Muscat privileges can comment on the record directly, tagging a Zentralredaktion staff member).
We do not accept IFLA vouchers as payment for photoduplication (or for any other service).
