[1] fifth line from the top in the History section:
"In condensed matter physics means that" --> "In condensed matter physics it means that"  

[2] second line from the bottom in History section:
"by Nambu and Jona-Lasinio (1960a,1960b)"--> "by Nambu and Jona-Lasinio (1961a,1961b)"  

[3] second line from the bottom in The Nambu-Jona-Lasinio model section: correct identifier of Weinberg (1967) should be #W

=== Reviewer A:  ===

The following is my comments to the article:

(1) In the section of The analogy with superconductivity:
Although $\psi_{1,2}$ are defined as the eigenstates of the chiral operator $\gamma_5$,
the same symbols are also used for the two components of the electron state in the Nambu
representation for the superconducting state. It might be bette to use a different notation. 
  
A period is missing at the end of the definition of $\Psi^{\dag}$.

(2) In the section of Nambu-Jona-Lasinio model:

I believe that the sign of RHS in the definition of the generated mass $m$ should be changed to minus, as
 $m= -2g[\langle \bar{psi}\psi -\gamma_5\langle \bar{\psi}\gamma_5\psi\rangle]$.
  
Correspondingly, the sign of the second line should be plus.
Please check them.
