The stock 74HC595 has a very unintuitive layout. The output pins are on different sides of the boards, which makes routing more of a hassle than it needs to be. I designed a breakout board to get around this issue.

VCC is pin 1, and is next to SRCLR on pin 2. I did this since you typically tie SRCLR high. Output enable is on pin 7 and is next to ground (pin 8), since you also typically tie output enable low. In between are SRCLK, RCLK, SER IN, and SER OUT. On the right side, from pin 16 and working your way down is outputs A through H.

Holes for an optional power supply filter capacitor are included if you want to filter transients and ripples.

This design is a more intuitive approach than the stock chip pinout. Enjoy!
