ISO 5459 and ISO 1101

[TED7]

Does anyone have a copy of both of the above standards to hand and can tell me the difference between them? I'm fluent in ISO 1101. But upon reading the ISO description for ISO 5459, it appears to be pretty much the same thing, graphical descriptions on how to attach datums and symbols to entities in drawings.

ISO 5459's title is "Geometrical product specifications (GPS). Geometrical tolerancing. Datums and datum systems" and ISO 1101's title is "Geometrical product specifications (GPS). Geometrical tolerancing. Tolerances of form, orientation, location and run-out"

I know 1101 covers the application of datums and symbols, so my question really is 'what does 5459 offer that 1101 doesn't?'

ISO 1101 is a general overview of the GD&T system (which is a part of the overall approach they call GPS).
ISO 5459 is more laser-focused on the application and interpretation of datums. (1101 doesn't really cover datums much; just a little over one page.)

I'd love to scan a copy of each and post them here for you, but copyright laws, blah, blah....

Getting hold of a copy isn't an issue but I don't think the boss will be too pleased about me buying ISOs just because I was curious what was in it. I will probably stick with 1101 for the time being, until the machinists and inspectors at least get their heads around the basic concepts. Thanks,
