To use lingo picked up from a library school friend, this is definitely "way sweet". The CONSORT Libraries (Denison University, Kenyon College, Ohio Wesleyan University, and the College of Wooster) catalog has the option to send yourself the location information of an item via a text message. For an example, see here. Click on the "?" for the disclaimer (i.e., based on your cell phone plan, you may get billed for the text message).
Don't want to write it down? Have it sent to your phone!
Is it a new feature from the catalog providers? Is it a hack? I don't know, but it sure is way sweet.
