I've been asked by our Curator of Rare Books to get feedback 
regarding bar coding of rare materials being sent to off site 
storage facilities. For those of you who send these materials off 
site: how do you attach a bar code? When rare materials are on the 
shelf, the bar code is attached to a card that lays in the book, but 
when put in a storage tray these cards may fall out. We don't want 
to attach the bar code directly to the item. One idea would be to 
attach the bar code to a piece of paper that wraps around the front 
cover. However, this will only work if the covers are attached and 
in good condition. What are people doing in the cases of detached 
covers or materials without covers?
Thanks.
