Looking for Studies on advantage of print

In preparation of this year's budgeting meetings, I'd like to present info that speaks to the advantages of print over online. We are a monthly business/association magazine, circ. 112,000
There have been some rumblings about putting the print product online only. We don't think that's a smart move. One thing I've noticed is that my print magazines stand out in today's mailbox. In an effort to save money,many are eliminating print (in any form, direct mail, magazines, etc.) and bombarding people with e-mail or online info.
Any studies out there about this? Thanks!
