This directory contains files of PostScript versions of the columns. After retrieving a file you can send it to a PostScript printer to get a hard copy or view it with a PostScript display program such as Ghostview.
If you are accessing the files with a web browser, the ".ps" extension will probably cause a PostScript viewer to be spawned. Or if you have no viewer configured for files with the extension ".ps", your browser may ask what you wish to do with the file. You can download the PostScript file, save it to disk, and then send to your printer.
The Titles of columns are listed below by date.
