Personal reminder service for library users

If your library is a Polaris PowerPac (v3.2 or later) or a Dynix library system (Classic or Horizon – excluding Java-based Dynix WebPAC) and hasn’t yet signed up for Elf, an Internet-based tool your users can use for keeping track of what’s due, overdue and ready for pickup for one or more library accounts, take a look at the demo.
Reminders are sent based on user preferences – before items are due (up to seven days advance notice, weekly notice or everyday reminders). For families or anyone who’d like reminders before an item is due (user-selectable number of days notice).
There is a list of those libraries already using ELF.
For those library users who have Macintosh computers, there is a a great OS X application, Library Books, that offers tracking as well as displays the information in the menu bar.
