I Don't Need A Personal Library Book Embosser

I was going through some used books the other day and noticed some of them included a personal library book embossed stamp on the first page. And the books had been owned by a few different people.

It occurred to me at that moment that it had never occurred to me in my life that I might want my own book embosser so I could include one of those round stamps in all my books that said, "From the Library of Stephen Leary."

What's the value of such a stamp, I'm now wondering. Vanity? A way to claim...
