I don't ignore it at all. My CD burner has a place of honor on my desk.
However, in
my trash bin are 5 1/4" floppies. I no longer have a computer that will
read them. Yet, five years or so ago, 5 1/4" drives were common.  Now
you have to consult a specialist to read them.  Documents created in CPM
(an operating system that preceded DOS, circa 1982) may not be readable
at all.  What is your guarantee that the CD's we create now will be
usable, readable, a few years from now. What if the master CD gets
scratched, tossed in the trash by a neo-luddite librarian or
administrator? What if it gets infected by a virus or worm and the data
thereon is destroyed?

Stipulated.  Personally, I accord conservation among the most honorable
of professions, one that should be offered in every school that teaches
Lest I be accused of fantasy bordering on lunacy, you might want to look
at the prices of original materials on the open market over the last
ten, five, and one years vs current prices in such forums as flea
markets, antique stores, used book dealers and of course eBay.  Interest
in original documentation has skyrocketed, as have prices, over the last
24 months as the internet has increased the ability to market to a wider

dissemination were given to the terrible crimes perpetrated by libraries
in tossing originals on the trashpile, perhaps more interest will be

This may come as a shock to some, but not all newspapers are printed on
highly acidic material. Most 19th century papers were printed on very
nice rag content paper.

And there are ways to arrest, stabilize or slow down the acidification
process that are not terribly expensive.

My grandmother was a rich old lady, and people lined up to kiss her.
Same thing
with these old documents. In their original form, they are extremely
valuable on
the open market (Check out the dealer prices for individual old
newspapers, magazines and other ephemera.)  Just to take matters to an
extreme, I recently sold an original 1971 New York Times clipping on
eBay for $141.00  (in order to preserve the integrity of the few hard
copy collections that are left, I won't mention bibliographical

Sexy, very sexy indeed.

As is digitization, a process that I applaud, welcome and perform.
Digitization is a huge, and extremely profitable business. Just take a
look at the huge numbers of databases and books digitized and archived
in the genealogy field.
see: http://www.ancestry.com  http://www.heritagequest.com

Then, you might want to take a look at the grants being administered
through the Library of Congress (privately funded from private industry)
for digitization of important collections. The terms of the grants state
that recipients can recapture the amount original grant by charging a
fee for access or reproduction, so that the process can continue.

However, I think my previous posts provided a rational and well thought
out basis for not discarding the originals once discarded, and there is
no need to repeat what I have written.
