Selected papers are available either in postscript [PS], compressed postscript [PS gzip], or acrobat PDF [PDF]. Your browser should allow you to save these files to your disk. With Netscape, clicking on the right button (or holding the button for Macintosh) will pop up a menu with options to save the file.
If the helper list on your browser has been set up with decompression software and viewers then you can view the papers directly by clicking on the link.
