Hi David. I think I've actually figured out the original published date being wrong, and it's not GR but Worldcat providing incorrect data.

For the following three ISBNs, if the checkbox in the configure source dialog for "Use published date of "first edition" (from worldcat.org)" is checked, you get incorrect results. Unchecked, it matches the (correct) data shown on Goodreads. It's quite specific to these editions, because they are in fact wrong on Worldcat.

9781101142349 provides 1962 from WC, expecting 1849 (per GR)
9780192806338 - 2003 from WC, expecting 1830
9781588363053 - 1993 from WC, expecting 1873

Since that is, I believe a Calibre-wide checkbox it would be wrong no matter the data source for those specific books (and the reason is simply because those particular editions haven't been linked to all the other editions for those books, whereas they have on GR.) I guess it turned up mostly in the GR plugin, simply because GR is one of the only other sources that routinely provides that data.

My only suggestion for anyone else hitting this issue, if you're getting the wrong result, toggle the checkbox, and try again (thereby hitting the other source for the data).
