Commas around author names?

[Scott]

Consider the two ways of punctuating the following sentences:

1-- I love the Book of Pretend Things by Tom Smith.

2-- I love the Book of Pretend Things, by Tom Smith.

In the lenient international non-style-guide-specific context of this International Grammar forum, which way is correct? 1 but not 2? 2 but not 1? Both?

For reference, in this lenient international non-style-guide-specific context, a sentence would not be gramatically incorrect just because one or two style guides say it is incorrect. Rather, it would have to be incorrect regardless of what major style guide one follows and regardless of what English-speaking country's vernacular is being used. For example color and colour are both correct spellings in the context of this forum, and the usage or non-usage of the Oxford comma are both correct in the context of this forum.

I tend to use 1 but I don't think 2 is incorrect? I'd say both are okay.

So writing "Executive Hoodlum: Negotiating on the Corner of Main and Mean by John Costello is a memoir..." is correct?

and also "Executive Hoodlum: Negotiating on the Corner of Main and Mean, by John Costello, is a memoir..." is also correct?

and also "Executive Hoodlum: Negotiating on the Corner of Main and Mean, by John Costello, is a memoir..." is also correct?

Both are acceptable.

Good to know! I was docked on a recent review for writing it without the commas. I have not used commas in any of my other reviews between the title of the book and the author's name and have never been penalized for it until now.

This issue is very helpful.

Personally, I prefer to use number 2. But in recent times, my professors in college told me that method 2 is strongly preferred. So because of social changes, I now use method 1.

I go along with your comment
