Can anyone point me in the right direction for a reference on abbreviations on a PCB board?

I know R means resistor and TB means terminal block. What are the other letters that can show up on a PCB and what do they stand for?

*Edit*

Just found this:

A = Assembly
B = Fan
BT = Battery
C = Capacitor
CB = Circuit Breaker 4-1
CR = Diode
D = Diode
DL = Delay Line
DS = Lamp
E = Terminal
F = Fuse
FL = Filter
J = Connector, Recept
K = Relay
L = Inductor
M = Meter
P = Connector, Plug
Q = Transistor, Semiconductor
R = Resistor, Potentiometer
RT = Temperature Sensing Element
S = Switch
T = Transformer
TB = Terminal Block
TP = Test Point
U = Integrated Circuit
V = Vacuum Tube, Neon Bulb, Photocell, etc.
VR = Zener Diode
W = Wire, Cable
X = Socket
Y = Crystal Unit
