I am [name] from [name] Publishing.
Would you be interested in publishing your work "Corrigendum: A revealed preference approach to valuing non-market recreational fishing losses from the Deepwater Horizon spill" as a paperback edition?
At [name]Publishing, we have worked with more than 250,000 authors, offering them international, free-of-charge publishing.
Can you imagine your work as a book?
The definition of corrigendum is "a thing to be corrected, typically an error in a printed book." So, yes, sure, I can definitely imagine my correction as a paperback book! Maybe a mystery where I'm the detective trying to uncover research errors of omission and suddenly I look in the mirror and find one of my own?
Actually, my reply was "no thanks."
