Yes, all schools offer westlaw/lexis, but some make you wait.
They are NOT just for "research" as someone said. The case briefs on lexis almost always address the issue that your prof will focus on. If you use them as you're supposed to use canned briefs, as supplements to the assigned material, they're perfectly fine, and easy enough to add additional info to. They are not useful as a substitute for the reading, but that's really not the point of any study aid.
Finally, there is a board for advertising and products. This crap belongs there.
