@kiwidude, thanks for the info. This isn't something I'll do a lot, so manually entering the data into columns would be OK. I was hoping that what I wanted to do had already been implemented.
At the moment it looks like my best option is to open the ebook in Calibre, select the main text of the ebook, paste it in to this site:
http://www.standards-schmandards.com.../rix/index.php, and then manually copy the two data fields to columns in Calibre.
I'm open to alternatives though.
