What must a custodian do if the record is not maintained in the medium requested?

The custodian is required to convert the record to the medium requested when it is not originally maintained in that format. This obligation ensures that access to public records is facilitated as much as possible, adhering to the principles of transparency and accountability in government. By converting the record, the custodian meets the requester's needs and complies with public access laws, thus supporting the right of individuals to obtain information held by public entities.

Other responses may involve providing alternatives or declining the request, but they do not align with the legal requirements for accommodating requests for public records. Choosing to provide a copy in a different medium would not fully satisfy the request, while refusing the request or simply notifying the requester that the record is unavailable would prevent access to information that should be made accessible to the public. Therefore, conversion to the requested medium is the most appropriate action to take.
