Some of these are spare glass shelves fom display cases (the edges are ground smooth and not sharp). Needs to be thick enough to not break and to provide necessary weight (i.e., no window glass!), but small enough in area for a person to handle (that eliminates a 3/4" thick glass door from a 1930's department store!). You could even get glass of desired thickness cut to order at any glass store very cheaply. We've used these shelves for years without an accident. People approach them with respect. Glass distributes weight evenly across the maps. If they've been rolled up a long time, you still might have a problem. --Mark ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Mark Thomas / [log in to unmask] / 919-660-5853, fax:919-684-2855 Economics, Geology, Geography Bibliographer Map and GIS Librarian / Public Documents and Maps Department 025 Perkins Library / Duke University, Durham, NC 27708-0177
