I aksed for all three versions (electronic, paper, download), and have only received the paper copy. It's easy enough to download from the NFPA website, but it appears they don't honor all requests...
Don, the front cover has the number 671-984-7246 for obtaining copies.
It's a little off topic but I received a catalog today from the NFPA with reservations for the new 2008 Handbook. Will be shipped in 1/08. Kind of a long time away to be reserving it now.
