At the University of Arizona if you happen to be using the full version of the UA Library Catalog, you can also text the title, call number and location of a book to your cell phone before going to look for it by clicking on the the "Send via Text Message" button!
Alexander Street Press has a similar option. Uses could stream music and videos to their mobile device! Just search them from your desktop or laptop computer and look for phone icons next to titles of individual selections. Clicking on the icon will open a window with options for access. These links are good for 48 hours.
