----------------------------Original message---------------------------- We keep old versions until the new ones are up and running. Then we recycle the disks and toss the manuals. We have never found a reason to keep an old version; they are not like earlier editions of books. Software usually supersedes what went before. Cataloging replaces one version with another. Licensing usually requires that only one version be in use. We recently found that dBase IV for a LAN actually makes the III+ files inoperable as it is loaded!! Clearly, producers do not intend for users to have more than one version around. Elizabeth Wood. USC Norris Medical Library.
