[PADG:2252] Re: Glue sticks & book pockets



Tyra,

Very thoughtful questions.  This was my general thinking when I decided to approve/recommend this product to the Yale community. As to workflow:  All new items destined for circulating collections that use the date due receipt are getting the pockets in shelf-prep.  We have literally millions of items in the stacks that either have (or don't!) the paste-in date due with the two columns.  As these are checked out, a pocket is applied by the circ staff.

Hope this helps.

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,

Tyra,

For about six months now, we have been using a newish product offered by Gaylord.

It's called a Perfect Pocket, and consists of a polyethylene pocket with an acrylic pressure sensitive adhesive.  It is sealed on three sides, the front is slightly shorter than the back, and the front is folded over to strengthen that edge and to make insertion of a date due slip easier.  A simple accelerated aging failed to show any significant interaction with any of the papers we tried it on--beyond the obvious fact that it is not realistically reversible.

Of course, nothing's ever "perfect", so we had Gaylord customize the pocket to make it wider.  The original design is fine for the standard old-fashioned date due slip, either the folder stock or typing paper kind.  However, many of our libraries at Yale have switched over to the cash register receipt type date due slip, and the paperstock is wider.

The guards really like the clear pockets because they can match the barcode on the date due receipt with the barcode on the book without messing with the receipt.  Also, the clear pocket doesn't obscure printed endsheets.  Circulation staff appreciate having a pressure sensitive pocket rather than something requiring applied adhesives.

Many advantages, but not reversible.
