E-journal pricing question

["Sloan, Bernie" <bernies@uillinois.edu>]

I'd appreciate some feedback on the following....especially from anyone
who has undergone a similar process.

An academic institution publishes a print journal. They include online
access to content at no additional cost to print subscribers. Under this
model, online content is available only to print subscribers. The
publisher gets an inquiry about subscribing to the online content only
(i.e., the inquirer doesn't want the print).

Assuming the publisher is considering unbundling print and online content:

1. What issues need to be considered when separating print and online, from
a subscription/revenue standpoint? 

2. Does anyone have a good pricing model, or suggestion for same?

Thanks!
