Smoke,
The "just have to look in the right place" is the answer. But...
If you want to "own" a copy, you're supposed to buy it from
the "appropriate authority" or their "representative". True for SAE,
and the others mentioned.
One big reason SAE (Society of Automotive Engineers, for any who were
wondering) standards are so widely available (and adopted) is the
size of their market, its' importance to the economy, and the LONG
time their standards have been around!
Relatively speaking, it's not the same for cnc. How about thinking
that each Gcode "flavor" is like a size, or type of bolt... And it
has not yet been decided WHICH bolt is "best" for certain things. But
as time goes on, these choices ARE being "discovered",
or "championed", and the variations (number of different sizes and
types of bolts) are "settling" towards the AGREED "best".
So, I believe we will "get there", but there will always be the 3
stages mentioned in my last post, exploration, settlement, and
structure.
Hope this helps.

3) As you say, they may be unaware of it, and derive their info from
previous mfr's (second-hand information, or worse)
Something the courts are having a VERY hard time with!
The standards ARE copyright-ed material and offered for sale, and the
EXPECTATION is that they will be purchased by those who wish to/need
to use them.
Traditional copyright law breaks down when you can have multiple
usage of the same document concurrently (As a book, GENERALLY only
one person can read it at a time, on the internet, MANY can read it
at the same time...)
As to "if its in a library, it could be on the internet":
Yes. But the "could be" is the right OF the copyright holder! ONLY
he/she/they have the "rights" to decide to allow "their" document to
be posted to the internet!
There is an allowance in copyright law for what is called "fair use".
This allows "excerpts" from most ANY copyrighted material to be used
freely. By anyone. This is another area the courts are having a HARD
time with...
Happy Thanksgiving!
