One whole wall of my childhood bedroom was shelving for books. I had hundreds of them: the entire Mr. and Little Miss collection, Dr. Seuss books, a set of encyclopedias, a set of medical encyclopedias, BSC books, Choose Your Own Adventure books, and even ones I wrote, printed and bound myself.

My room was a library with a bed. Each book was carefully labeled as mine. At some point, I even instituted a library and borrower’s card system to make sure books were not lost when people borrowed them.

My mom came up with a (not so) secret method of marking each and every one of my books. Don’t you dare claim that book is yours, because I know how to prove it’s mine! To this day, I still flip to Page 45 of my books. Here’s a peek at the last few books I got from her.
