Publishing a Corrigendum? I recently published a book chapter with my supervisor. I just realized that I messed up two dates in the chapter. For the first one, the original sentence is like "xx policy decisions were published in 2004", but the year should be 2015. Another one "xx policy will be abolished in 2013 ", but it should be 2023. 

The chapter is now published online and in hardcopy. 

I wonder whether it's necessary to submit a Corrigendum? The book chapter is about reviewing the current literature on a specific topic (not an empirical study). I worry this will affect my reputation.
For minor corrigenda (such as this), some scholars merely put it on their web site.  Likely many of your future papers will also have errors, so keeping a list of all of them in one place may be the best choice.
