For anyone looking for "archival" storage of image (or any files) on CDs or
DVDs, consider this: while manufacturers make various claims for longevity
of the media, there is no assurance that the equipment will be available to
read that particular disc in 25 or 50 years (or even 5 or 10). Remember 8
track tapes? Remember 8" floppies or even 5.25" floppies?
Keep in mind, also, that there's a strong likelihood that you're going to
have to migrate to a new "standard" file format down the road. Where is it
easier to manage your files--on a big network drive or on hundreds
(thousands?) of CDs, DVDs, and other removable media? A stable, secure
network, good file management, regular tape backups, decent metadata, and
error checking software will keep them as safe as we can hope for at this
early stage in the digital world.
You can store CDs and DVDs in stable, climate controlled storage, in
acid-free sleeves or non-reactive plastic cases, but none of this will make
them an "archival" backup. Archival means permanent, or as near as we can
get to it. It's pretty easy to define what makes a paper document "archival"
and store it in such a way that it'll be usable for the next century (at
least). We're in the early stages of defining "archival" for digital files:
keep your eye on what's going on in the digital preservation world and
follow in the big guys' footsteps as much as you can.

Why do you want to use CDs to store images. The maximum size of a CD is 700
MB, only good for a few digital images.
We use hard drives only. (Forget about DVDs,they are not good for long-term
storage).

Subject: archival storage of CDs
After a year on the job I have collected loads of digital images -
scanned, shot, donated. It's time to put the master files in storage.
Is there a general consensus on what materials to use? What type of CDs?
Is there a specific pro or con to use CD envelops (compacter) or jewel
boxes (more rigid)? Does anyone have good experiences with specific CD
drawers/boxes/cabinets? Is there anything I am overlooking here?
Any and all comments are appreciated!
... and a good new year to all!
