Unfortunately for me that my whole library is pretty much 99% non-fiction books and mostly math, tech, and travel books which have many editions. I respectfully disagree with you Kovid, about the per edition published dates not being useful. The published date of each edition is also what makes each edition unique. If I own a 1st edition and 5th edition of a particular book. It doesn't look right to have them both shown with the same original published date when they are 20 years apart.
I'm not savvy enough to write a patch for Calibre, so I guess I'll just do it the manual way or until some kind soul can write a patch. Regardless, I came from Music Collector and find Calibre much more robust, so many thanks to you Kovid!
