I own the USGS "bible" on map projections. Not a library, but it has

We have a library of java routines coded mostly from Snyder's book. Nathan, if you code something that we dont have, we probably want to add it.
Yes, I have that as well, and it was really simple to use it. But, what
I would like is a general library of code that OPeNDAP can adopt so
that we can do two things:
1. Not write (re)projection code ourselves; and
2. Build up knowledge within the group so that we don't each spend time
(re)learning the same stuff.
This just seems like such a basic problem, it's hard to believe
everyone codes these themselves.
Maybe I just need to print the libproj docs and spend an evening with
them.
libproj I think is pretty standard for C libraries, but there may be some question about if anyone is supporting it.
The CF standard refers to it, and points to docs at

I've looked at libproj, but it's not obvious how to get it to work
with my application.
Thanks,
James
