If you click on the name of the paper and have an appropriatereader, itwill appear now. The newest papers are available in pdf format on this page. Some of the older postscript files can be obtained by anonymous ftp (loginname"anonymous" or "ftp"; password can beanything)fromftp://www.math.uic.edu/pub/preprints/baldwin/. You will need to uncompress these files with the command pkunzip or gunzip. In those cases, the name of the archived file is in parentheses.
