How should I list Internet sources in my bibliography?

The Internet presents an additional challenge when it comes to listing online sources in your bibliography. Newer editions of style manuals are beginning to include suggestions for citing information from web sites, gopher collections, ftp files, usenet groups, electronic mail, etc. There are also Internet sites which provide guidelines for these types of materials.
