The Open Group hosts hosts a searchable, hyper-linked form of the specification.

Here is the 2024 update:

https://pubs.opengroup.org/onlinepubs/9799919799/

If you go to the Main Index there is a link to a Downloads page where you can get a tarball of this stuff in some shape or form for local use.

Vast difference between this and the paywalls put up by ISO and their member organizations, and their free PDFs that have only tables of contents.

You mean free pdfs like C and C++ drafts?

https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3220.pdf

https://isocpp.org/files/papers/N4860.pdf

Maybe like Ada,

http://ada-auth.org/standards/ada2y.html

Or Fortran,

Apparently there is a little more than a table of contents, when people actually know where to look.

Funnily enough, I had ended up contributing to POSIX without trying to. I just participated in mailing list discussions and in the public bug tracker (reporting issues, commenting on tickets etc), for which I only needed to register a no-strings-attached account -- the absolute minimum for participating in any bug tracker. Unexpectedly, I got named in the "Participants" section of the standard. My head is still spinning.

Here are some links for you:

- SUSv3, 2004 Edition: https://pubs.opengroup.org/onlinepubs/000095399/nfindex.html

- SUSv4, 2024 Edition: https://pubs.opengroup.org/onlinepubs/9799919799/

I don't know where the SUSv1 PDFs are, I have local copies; but in 2025, they're at best of historical interest.

It shouldn't be easy to contribute to POSIX. That shit needs some serious gatekeeping. It's not a side-project whose goal is self-actualization for all participants. The requirements get foisted on everyone and last decades.

I agree with you about the seriousness and heft of POSIX (and I definitely know your name from comp.lang.c[.moderated], so I respect your opinion); however, there is no arbitrary gate-keeping around POSIX. If anyone is willing to put in the time and effort, they're welcome to join. This couldn't be more different from other standards orgs where you can only join as a (voting, or observing) representative of an employer that pays an exorbitant yearly membership fee.
