To start with, I'm stuck in section 39 on working out the anti-commutation relations for the creation and annihilation operators. For example, take the calculation at the top of pg 246 (eq 39.16)

[itex]

$\{b_s(\textbf{p}),b_{s'}^{\dag}(\textbf{p}')\} = \int d^3xd^3ye^{-ipx+ip'y}\{\overline{u}_s(\textbf{p})\gamma^0\Psi(x),\overline{\Psi}(y)\gamma^0u_{s'}(\textbf{p}')\}$\\

$=\int d^3xd^3y e^{-ipx+ip'y}\overline{u}_s(\textbf{p})\gamma^0\{\Psi(x),\overline{\Psi}(y)\}\gamma^0u_{s'}(\textbf{p}')$

[/itex]

Srednicki starts with the second line, but how does that follow from the first line that I have written?
