We came across this "go green tip" from UC San Diego and just had to share it:
UCSD has developed a online feature that allows students to click a "Send by Text Message" button on while browsing the online Library catalog. Within seconds, students will have a new text message that includes the title, call number, and location of the item they wanted! Students can then stop by the library on their own time and reference the SMS message to quickly find the book.
