Will online archive access lure subscribers?

From Poynter Online: Columnist Steve Yelvington predicts that newspapers and magazines will offer archival access online to customers in an effort to keep circulation numbers high.

The leading newsweeklies, Time and Newsweek, currently differ in their online access; while Time offers portions of its content on its site, Newsweek is embedded as a section in MSNBC.com.
