[Tutor] Problem with Reference Manual (duplicate ISBN)

[Tim Johnson]

Nope, I'm not criticizing the writing or the technical info at...
Just the sloppy publishing.

I ordered the Reference Manual for Version 2.5 and got Version 2.3
instead. 
Reason, they have the same ISBN. The vendor said that this is
very unusual.

This should be corrected, don't you think?
