The Internet Fax FAQ
The granddaddy of internet fax FAQ's, this page was created in 1994, and looks like it! Unfortunately, appears to only have been kept updated until December 2016, but, still, has very useful information.
From their outro: "The editor and contributors have developed this FAQ as a service to the Internet community. We hope you find it useful. This FAQ is purely a volunteer effort. Although every effort has been made to ensure that answers are as accurate as possible, no guarantee is implied or intended. While the editor tries to keep this document current, remember that the Internet and its services are constantly changing, so don't be surprised if you happen across statements which are obsolete."
