Truseted list of EtherType number in Ethernet Frame

[skwo]

Hello I'm looking for Well-Known value of the EtherType in Ethernet Frame.
I found this links:
http://en.wikipedia.org/wiki/EtherType
http://www.iana.org/assignments/ethernet-numbers
http://www.cavebear.com/archive/cavebear/Ethernet/type.html
(2-nd actually based on 3-rd)
As you can see there are differences between them.
Anyway what I need is a trusted Source to take the EtherType values from.

Thanks a lot!
