Making your CD/DVD's last longer
The Council on Library and Information Resources is an organization dedicated to Library Sciences. They have an excellent article on the Care and Handling of CD/DVD's. Many people are using these devices for everything from computer backups to storing the family photos, but few people are aware that CD's (and DVD's) may not last as long as they think. This article is pretty technical, and goes into a lot of detail as to what can ruin a CD (like flexing it too much to take it out of the jewel case!). I suggest checking it out if you are using CD/DVD for backup/archival purposes.
