In the story Vincenzio the Venetian, I mentioned that the name 'Retszch', as spelled in the source, should in fact be 'Retzsch'. Now the page will be found in any search on 'Retzsch'.
After that, I made various PGN corrections brought to made my attention over the past few years. They can be found by looking for the date of this post in Index of /chess/pgn. Thanks to everyone who flagged the PGN errors.
