A free viewer for .pdf files, Acrobat Reader, is available from Adobe . A free viewer for MS Word documents, that lets you print them as well as see them on screen, is avialable from Microsoft.
I can also prepare zipped postscript versions of the files if necessary.
This may be helpful to you if you have font trouble with the pdf format
files and if you are regularly using postscript with mathematical fonts
on your own computer. Let me know by email if you have failed to get a
readable version of the Word or pdf format file and would like me to put
up a postscript version.
