Below is an old photo of most of my chess books,
several of which I've now owned for more than 43 years!

In all, I have 621 different titles.

The bottom shelf contain my Chess Life magazines.
I have a complete run from October 1971 to the present. 
In addition to that, I have dozens and dozens of issues from the early to late '60s.

I once remember thinking I had a lot of chess books...
until I started hanging out with other chess players
and hearing of the size of their collections!
