[PADG:1023] Follow up to a question during Photo. & Rec. Media DG

["Werner C Haun" <whau@xxxxxxx>]

Following up on question asked at the PARS Photographic and Recording
Media Discussion Group, here's a summary and link to a thorough
article by Caroline Arms on how the Library of Congress is
mainintaining/preserving its files of digitally reformatted
photographs, texts, maps, etc.

 Arms, Caroline R. "Keeping Memory Alive: Practices for Preserving
   Digital Content at the National Digital Library Program of the
Library
   of Congress" RLG DigiNews 4(3) (June 15, 2000)
   (http://www.rlg.org/preserv/diginews/diginews4-3.html). - It is
likely
   that the Library of Congress is overseeing the single largest
library
   digitization effort on the planet (producing over 14GB of new
digital
   files per workday). And what luck for the rest of us -- they
   frequently share what they learn, the processes they create, the
best
   practices they set, and even their Requests for Proposals (RFPs)
to
   digitization vendors (see http://memory.loc.gov/ammem/ftp 
   files.html). In this article Caroline Arms continues her tradition
of
   promulgating information vital to those attempting similar
projects
   (for example, see other articles of hers cited in Current Cites).
   In this case she describes LC efforts at preserving the digital
   material that LC is creating while building a National Digital
   Library. Of particular use is a chart that briefly describes all
the
   current accepted digital preservation methods, all of which may
be
   logically employed in the course of preserving any particular item
or
   to recover an item that hasn't been properly preserved by using
these
   methods. - RT [Roy Tennant, UC Berkeley]
