Hi again I played around with the ISBNdb OpenRefine queries to extract the minimum price from their database. I had to parse the returned JSON code to do this. In case you are interested, I've published these operations here: https://gist.github.com/timtomch/34bc2c4c9666cf9bf011 They can be applied to your project by using OpenRefine's "Replaying Operations" function: https://github.com/OpenRefine/OpenRefine/wiki/History#replaying-operations Have fun, and let me know if you're having any issues.
