If you've taken to visiting the local library as a means of cutting down on book clutter, you could well be faced with a new organisational challenge: keeping track of which books you and family members have due. While most libraries offer online tracking for books these days, if you're using multiple libraries or can't get email reminders, then Library Elf could be useful. The basic free service send email reminders for due dates, but is restricted to just one library; there's an optional premium service if you regularly haunt multiple libraries, and which is also available from participating "subscriber" libraries without cost. By my count, there's 57 Australian libraries currently included in the service. If you've got another tactic for making sure you don't get hit with overdue fees, share it in the comments. Thanks Tim!
