ar is a non-compressed archive format for Unix-style operating systems. It was mostly superseded by tar for general archiving use, but persists in use for specialized applications involving linkable libraries for development.

Overview
There are at least 5 different variants of the ar file format since it has never been formally standardized: AIX(big), AIX(small), Coherent, BSD, and GNU.
Examples
To list the contents of an archive, using the ar utility:
$ ar tv example.a
To extract the contents of an archive:
$ ar xvo example.a
Software
- GNU Binutils → ar
- llvm-ar
- Deark

- IBM AIX documentation on scribd here (page 386+; someone might find a better accessible version)
- Also from IBM is this description (and this for the "small" variant)
- The Microsoft PE/COFF documentation also has a section on .lib files which use the same format
