Chicago Tribune:  http://www.chicagotribune.com/news/corrections/ or try a search for ct-claris (apparently an abbreviation for “Corrections and clarifications”).  On July 14, 2013, the html page title and content heading of a given day’s page is “Corrections and clarifications for Sunday, July 14, 2013.”  The URL for that day’s sole correction is http://www.chicagotribune.com/news/corrections/ct-claris-071413-20130714,0,2039543.story.  An address for a day with multiple corrections is http://www.chicagotribune.com/news/corrections/ct-claris-062113-20130621,0,7352554.story.  What the gibberish after the date in the address is is anybody’s guess.  It isn’t like there could be multiple corrections pages for a given date– and they need a unique identifier.
