----------------------------Original message---------------------------- Tom, Contact any blueprint company or office supply company in your area and they will be happy to give you lots of information. Also, your institution's purchasing officer is usually willing and able to help with source information and your library's business reference section will list many sources. Most have 1-800 tel numbers and publish catalogs which they will send by return mail. Prices may surprise you on this equipment; many institutions require that such purchases go out to bid and so the process can take a while. Good luck! Chris Ziegler Univ. of Az. Library
