Viewer for UNIX

I am not sure this is the right place to ask, but I hope somebody in this list will know:

I am looking for a place to find Viewers of documents like Adobe's Acrobat,
Does anybody know where (apart from Acrobat), I can find viewer 
that enable to exchange documents, running under UNIX System V.4?
Is there a forum discussing these?
Thanks
Alain
