To my knowlwedge, the only compression suite in the public domain is LHARC.
That is, if you want to include compression and inclusion into a library
in your commercial package, only LHARC will do - you would need a 
licence or at least permission from the copyright holders for any of the
other packages.

However, if you only want to uncompress a library that you have prepared,
then the situation is very different. Certainly Rahul Dhesi's zoo and
pkunzip, and even arc format uncompression from libraries are all PD, 
and may be used. 

Sources for all these can be found in the SIMTEL20 archives: 
check out:
the <MSDOS.ZOO> directory (3 files needed)
<MSDOS.ZIP>DEZIP20.ARC ZIP extractor with Turbo Pascal 5.0 source
<MSDOS.ARC-LBR>LHARCSRC.ARC TurboC/OPTASM source code for LHarc & its SFX
 
and other files in these three directories. Good luck.
You might also look at <MSDOS.CATALOG>PIBCAT17.ARC which has pascal 
sources for unpacking most things.

Hope this helped,
