Many documents in these pages can be obtained from ftp.math.utah.edu (128.110.198.34). Login as anonymous, use your complete e-mail address as password, and connect to /u/ma/alfeld. The files in the subdirectories there correspond closely to what you see on these www pages, and you can find their names if necessary by viewing the sources of the www pages. Therefore I'm not maintaining any README files.
Send me e-mail if you need any additional information.
