RSS -- "you have an overdue book"

Now that we are looking at email notifications...

From the LibraryStuff blog

"Libraries send many hundreds of thousands of notifications and communications to users a year. New technologies allow real-time (or near real-time) communication and are cheaper than sending letters. How many libraries have yet switched to new methods of communicating with users? In the HE arena, notices are typically sent by email, but this still requires students to check for new emails. How many have yet started to investigate technologies such as RSS and SMS?"
