Library -- Lifeblood!

If you're a thinking person, access to a library is the lifeblood of your world, too!

Above is my childhood library card, from good ol' Bartlesville, OK.

We moved to OKC, and I became a patron of the Metropolitan Library System.

There was a pocket in the back endpaper of each book, into which was slipped a card stamped with dates.  The most recent date was when the book was due.  Of course, these cards were inserted by hand by a friendly wise person.

In the 2000s, the cardboard date-stamped cards were replaced by paper slips.  The month was punched, then the due date.

Nowadays, you receive a printed receipt which lists the books you've just checked out, with the due date.  Of course, in this new age you check your account online, and receive a friendly email "Coming Due Reminder" a few days before the day arrives.

Best of all, checkout time is now THREE weeks, not two!  No excuse to not finish that book, buddy!  Get to it!
