I've noticed that some people (Matthieu), even mods such (Mark Trapp) keep adding the text 'Is there a canonical book on..' on many book related questions. Sometimes fundamentally changing the question that was originally asked. Sometimes the person asking the question justs want a list of resources to follow in reading, not one particular volume that he must read and which is considered canonical.
Also this is highly subjective, one person's answer to what is canonical may differ wildly to another's.
Is there any good reason for these edits?
If we are searching for a canonical text on any given subject shouldn't there just be one community wiki question with all others closed as exact duplicates? I can't understand why these words keep being added to these questions.
and on and on...
