One of the best programs for increasing reading speed is Ultimate Speed Reader, originally published by Davidson, which then became Knowledge Adventure. The program was out of print, but I have found a reliable resource for the product at Smart Kids Software: http://www.smartkidssoftware.com/home.shtml
They are currently listing the program at $247.95 for a 15 site license, and $559.95 for an unlimited network license. They also sell stand alone versions. If you have been searching for a source for this program, I contacted them today and they said they have the program in stock. Their phone # is 888-881-6001 for more information.
