I was looking today for a link to the National Postal Museum's downloadable "A Stamp for Every Country" downloadable PDF stamp album, for one of my veterans.

I spent a lot of time searching NPM's website, the Interweb in general. I was about to give up when I finally found it, on an APS web site with a large number of downloadable stamp albums to peruse:
