CCIE material on Books24x7

Excellent1

This information is probably already well known by those with subscriptions to Books24x7 (if you read the emails), but there are now 2 new CCIE level resources available:

CCIE Routing and Switching v4.0 Troubleshooting Practice Labs

and

CCIE Routing and Switching v4.0 Configuration Practice Labs (ebook), 2nd Edition

Anyway, just tossing it out there for awareness. These two titles are obviously above my current abilities, but given that I'm working on the CCNP now, I still get some use out of these, even if not to the extent that some of you folks will.
