Acroread 7 for Linux (18 Mar 2005)
Hopefully this one will stay around for a little while longer: Acrobat Reader 7 for Linux. The last release disappeared very quickly.
Why would you want this? Well, acroread is the bet quality PDF renderer around I'm afraid. It's big, statically linked and note very fast. But if you're reading a big PDF on screen it's probably worth it.
(Note: once installed goto the Reader/intellinuix directory and rename plug_ins to plug_ins_disabled. It starts much faster, takes less memory and I've no idea what all those plugins do since it seems to work just as well without.)
Update: It was released to help "people in the Netherlands meet tax deadlines"
