From the ResourceShelf site, and a link to the ACRL FAQ.
On April 1, 2011, the online version of C&RL (http://crl.acrl.org/) will become open access. A print version will continue to be available through a paid membership in ACRL or through a paid subscription to C&RL. Discussions about the future of the print version are underway.
ACRL has removed all price barriers to the content in the online version of C&RL. Any reader will be able to access current C&RL articles and backfiles from 1997 online without need for a subscription.
Way to go, ACRL!
