[PADG:2251] Re: Glue sticks & book pockets

["S. Tyra Grant" <stgrant@xxxxxxxxxxxxxxxx>]

Erika,
Since these Gaylord pockets are transparent, are you concerned about the
adhesive over time causing damage and pastedown discoloration (bad
enough) that would then show through the transparent cover?---I'm
thinking 20,30 or more years....  Do you have reason to believe this
(discoloring) might not happen?  Or are you able to think
around this somehow---e.g., by considering various trade-offs w/downsides
of traditional pockets? 

One more question for anyone---do any of you apply pockets at circulation
the first time the book is checked out (rather than during
processing)?  It seems that the easy-to-apply adhesive on these
pockets might make pocket application at first circulation possible and
save those books that are never borrowed.  Just a thought.

Thanks for this information,
