They decided to use the issuu web site for their existing digital files for the magazine. For the previous non-digital versions rather than OCR they plan to simply scan them in and present them as images behind a user login.
It's certainly not optimal imho because I believe rights management isn't there - just a simple login, if the user is sophisticated there are tools to download the SWF to their local computer and then they can republish it anywhere. But they said they haven't seen any republishing of their stuff in the several years they've used it for other items. One of the things on my plate is to setup an account for them with a duplicate content service to try to keep an eye on things after the transition. Not the best, but it's what will fit in the budget.
What basically happened is the more information I gave them the more their faces fell as they realized there is no cheap way to get so much content online (nearly 20 years worth) in a very secure environment.
