Thank you very much to correct me on this issue!

I did know the DocID existence but I did not realise,
until now, how it can be proved helpful. From the URL
you gave us for Richmond's report:

| http://hdl.handle.net/2060/19740013743

I found that 'hdl.handle.net' is a 'Handle Server', and
from NTRS item for this paper, I see that 19740013743 is
its DocID. In this way, and by experimentally replacing
this DOcID with '19890004330', I got the report titled
"Radiation and scattering ...". May now I think that
'2060' is some kind of ID in this Handle System for NTRS?
Where can I find more such IDs? Would you please advise me
more on this interesting subject?

It seems that this is a somehow complicated matter...

Well, there is a basic FAQ he
http://www.handle.net/faq.html
http://www.handle.net/overviews/handle-syntax.html

where I found that in the referenced by Jim Lux:

| http://hdl.handle.net/2060/19740013743

or in:

http://dx.doi.org/2060/19740013743

the couple of numbers '2060/19740013743' forms indeed
a unique 'handle' of which the two parts (numbers)
are known as:

Handle Prefix/Handle Suffix

or as

'unique naming authority'
/
'unique local name under this naming authority'.

Anyway, after I found
'The Internet Engineering Task Force (IETF)', of which:
'The goal of the IETF is to make the Internet work better':
http://www.ietf.org/

it made clearer that there is a registration procedure of
'naming authorities', as well as and this is definitely
a work which currently in progress, since on July 12, 2010,
the registered Name Assigning Authority Numbers (NAAN)
are only 54:
http://www.cdlib.org/services/uc3/naan_table.html

while among of them there is no NAAN for NASA or NTRS.

Anyway, this is really a very helpful reference system
for the Internet, but only *after* someone have search and
find the document which looked for, along with its unique
handle, of course.

Once again, thank you very much Mr. Lux for pointing out
this very interesting issue!
