Pursuant to a post on public libraries, I received a fabulous library tip from a father of twin toddlers.

Family expansion likely correlates with exponential increase in overdue books; if this scenario sounds familiar, check out the Library Elf. Sign up for this free service and input your library card numbers; the Elf sends you a reminder e-mail (or SMS to your phone) a configurable number of days before books are due, and continues to send a daily reminder until you return the book.

Check Library Elf’s list of libraries; they serve an impressive number of library systems in the US, Canada, and internationally.
