Elf reminds you when library books are due
Joel leans on tech to avoid library overdue fines:
Elf is a free service that works much better than taking out sets of five. Assuming your library is on the list (and they have several hundred of the largest libraries and library networks), you enter your library card number and PIN -- and the library card numbers of your spouse and children. Then you can get an email reminder whenever a book on any of your cards is coming due, three days ahead of the date (you can set the number of days, too). Or an SMS message. Or use the RSS feed. It has hugely reduced my overdue fines.
