Although it's more anecdotal (rather than statistical), fan mail can
help make a convincing argument that certain services are worth
continuing. Here at our library, I've seen both e-mails and
snail-mailed letters gushing with thanks for help at the reference
desk, thanks for a specific digital collection, thanks for an in-depth
research consultation. Some of these are sent to specific staff, and
some to the library as a whole.
Our library director usually reads one or two or these aloud at our
all-staff meetings each semester, so I know she sees value in them.
