I just got my Sony 505, and I'm really pleased with how easy calibre has made working with the device considering I'm on a mac. I'm curious about modifying a recipe for the New York Times news feed. The included recipe downloads a number of sections from the times, most of which I'm not interested. For example, I'd like to include the science section but not the sports section. When I looked at the recipe, I couldn't figure out how it was specifying the particular sections. Any ideas? Thanks in advance.
