Question Regarding Scott Internal Blue Album

Having had a brick and mortar store for nearly 30 years and having had a corporate Amos/ Scott account for all that time, the general answers are that changing corporate ownership and changing editors and thus editorial content over the 100+or- year lifetime of the Blue International have, of course, seen changes in content, country name, and other features of the product. The increasing retail cost of both the catalogues and the albums has had a profound effect as different collectors have different needs and different opinions as to what should or should not be contained in this particular product. For example most customers, and Blue collections we purchased over the years, had the pages resorted by country name.
A few comments on particulars raised: In the 1960s and 1970s the editors did take a " purist " view of what postal issues were legitimate and what were not. Thus the conflicts in Paraguay, Panama and the " sand dune " country listings, as well as others at various times. The current thought seems to be to include most issues in the catalogues for "established" countries ( for lack of a better word ) like the South American issues, but adding them to the catalogues alone has been a long term effort, much less the albums. Secondly changes in the political realm such as laws forbidding the importation of stamps from Cuba, the PRC, North Korea, Iran, etc creates headaches, especially in the US. European countries have not been as bothered as US politicians are to exclude some countries postal issues from collectors. And finally as someone mentioned, given the demographics of the US collectors base, it is amazing Amos still produces as many products as they do. Unlike Linns, albums and pages need to be printed to be used, unless we all start just collecting stamp images or stamp NFTs. My partners and I closed our store in 2017 mainly because our local customer base died off, literally.
I always have considered myself as one of the younger collecters and dealers in the hobby locally. But now I am 72, and next year I get my 50th year APS member certificate. Getting old is crap, lol.
