         abort(0)

while 1 do
         line = gets(fn)
         if atom(line) then

-- I dont know the significance of "<done>" in the data, so I'm removing it.
for i = 1 to length(text) do
         line = text[i]
         l = length(line) - 7
         if match(" <done>", line) = l + 1 then
                 text[i] = line[1..l]
         end if
end for

sequence uniqueUrls  uniqueUrls = {}
printf(1, "collecting uniqueUrls...\n", {})  t = time()
for i = 1 to length(text) do
         if not find(text[i], uniqueUrls) then
                 uniqueUrls = append(uniqueUrls, text[i])
         else
                 printf(1, "DUP FOUND: %s\n", {text[i]})

uniqueUrls = sort(uniqueUrls)
pretty_print(1, uniqueUrls, {2})  puts(1, "\n\n")

This spits out one duplicate: DUP FOUND: http://www.ed.gov

Also, I noticed such things as:

"http:// www.buydirectory.com"  has an embedded space;
"http://www.hub..terc.edu"         2 periods in a row;
"http://www.iee org.uk"              has an embedded space;
"http://www.ipl,irg/reading/books" has an embedded comma

Sorry for the delay.  I was trying to come up with a solution that wouldn't 
take hours to run.
Please tell me if you want me to continue.
