Hi all, First let me state that this repair suggestion for raised relief models is TOTALLY non archival. Tape! Over time the plastic gets very brittle. It becomes next to impossible to keep them pristine. Designed obsolescence? Could be. You just grab the model by its edge, and it comes off in your hand. We here at BYU have mounted them on cardboard, as well as taken them to our preservation lab looking for ideas. Storing vertically out of direct light does help. But since we had no real preservation options, our objective became simply to extend usability, and stop the cracking. So we simply used Mylar packaging tape on the back only, as well as along the edges. Again, to keep shards from falling on the floor. This use of tape makes many of us, including myself, cringe. But I've found few other options from a cost benefit perspective. All our preservation methods are quite involved and expensive. Mounting on cardboard kept them from flexing and cracking in the middle, but that too involved tape. Please, if anyone has a better solution, share it with us. Be gentle. Don't think too harshly of my suggestion. :) Thanks, Rick Grapes BYU Map Cataloger From: Maps-L: Map Librarians, etc. [mailto:[log in to unmask]] On Behalf Of Redmond, Edward James Sent: Wednesday, April 11, 2018 1:23 PM To: [log in to unmask] Subject: Re: map question Is this one of those 1:250K plastic "bumpy" maps put out by Hubbard Scientific? I have never ever served one to a patron as I see little or no reference use for them. Perhaps model airplane glue instead if Elmers?

It seems they have a 1972 Hubbard Relief Map that "got a little torn" and was wondering if I knew anyone who could repair it. I don't, off the top of my head. I think if I were in that situation it probably wouldn't occur to me to find someone who could repair it. I'd probably get out a jar of Elmer's glue and start sloshing away at it myself. But I'm only tangentially a map librarian. What would you all do? Mark Anderson Associate Professor of UL Research Services Librarian for Government Information, History And Geography James A.
