I'd like to point out a newly published stamp article on different approaches to Collecting the World in Linn's (now online, with printed copies being mailed to subscribers). The title is:
"If you want to collect the world, find a way to make it work for you" in Linn's Stamp News, September 20, 2021 (monthly issue) pages 103-106. The subtitle for the article is "a representative collection of stamps from around the world might help you discover intriguing new collecting areas to pursue."
Discussion (with illustrations) includes Scott International versus Minkus Supreme Global albums, plus the addition of extra pages for multiples, items on piece, etc.
