Gary, so far we don't have know what will happen after the trial period--it depends, in part, on what folks who try it out think and on how many users it attracts.

So we'd love for users to give it a try, even though it may mean you may not have access to it for free afterwards.

For what it's worth, if you love it but Duke does not get a site license, you can pay RefWorks for an individual subscription.
