If you work with PDF files, you can view them with acroread, FoxitReader or gv, or convert a Postscript file to PDF with ps2pdf on the Linux machines.
All of the Windows machines have Microsoft Office installed. OpenOffice (a free ``clone'' of Microsoft Office) is available on the Linux machines for dealing with Word documents under Linux.
I am happy to install any freely-available software which you need for your work. To help me with this, please let me know where on the Internet it can be found.
