Feature Coveting

OK, we already know that Ryerson University Libraries must be a cool place just from their slick Facebook app. Now, I've noticed that you can text yourself the title, location and call number of anything in their catalog. How cool is that? You just find what you want, click the little "send via text message" icon that appears in the record and off you go. Seems really handy!
I do have one concern about this...what happens to the cell phone number that I enter into this site? Is it being stored, erased, or what? A little note about that would be helpful.
Kudos Ryerson, you're ok in my book...even if you do spell catalog with extra letters.
