General ⇒ Difference between using quotation mark and curly braces?

[alwayssmile68]

Hi, What's the difference between using quotation mark and curly braces in a filed in a bib entry. See the following three cases which uses quotation mark, single curly brace and double curly braces respectively. Do you know how they affect the output? Thanks.

The differences are rather subtle. Check out for example http://artis.imag.fr/~Xavier.Decoret/re ... mmary.html for details.
