I am practicing making citations of quotes and I am currently stuck on publication dates.
To illustrate my issue, let’s use this this book:
The front pages state the copyright date as three separate years, which I have no idea how to interpret (see image below).
I checked on Google, and I found this on Amazon stating the publication date of Aug 10, 2010.
Checking the official site of publisher, I see "© 2011".
Do I need to make assumptions when taking the date, e.g., taking the first date from copyright without being certain that it is the correct publication date? I know I can contact the publisher and ask, but that seems like (a) a lot of work and (b) it’s pretty unlikely I’ll get a reply. I want to know if there are any tips on making sure that the publication date of the book is correct.
