"We have problems with certain students downloading 19 gigabytes of stuff,"
Susan J. Foster, the university's vice president for information
technologies, says with some exasperation. "What is a student doing to
download 19 gigabytes? What is that -- the entire Library of Congress? It
makes us think that it's video."

Obviously Dr. Foster was speaking metaphorically, but those
Delaware freshmen transferred about 1/1000th of the Library
of Congress -- or a dozen movies in digital form.

Brewster Kahle (Internet Archive, Alexa) estimates that if every
book in the Library of Congress were digitized, it would require
about 20 terabytes of storage.  This is text-only, no images.
So at 19 gigabytes the Delaware students have downloaded less
than 1/1000th of the Library of Congress.

On the other hand, a DVD holds about 5 gigabytes of storage.
Assuming the students are sharing movies in compressed
form, let's call it 1 gigabyte per digitized hour.  Thus
the Delaware students have transferred about 12 movies.

If you thought Napster could swamp a campus network, imagine
what Moviester could do -- or is already doing.

PS --

Many citizens assume that the Library of Congress has already
been digitized.  It has not.  Only a tiny fraction of its holdings
have been digitized.  There are no plans within LC to digitize
all of its holdings, or even all of its book holdings, or even
a substantial portion of its book holdings.
