Just got the 2022 Scott Specialized Catalogue of US Stamps and Covers.
To my great surprise, two previously present sections have been removed.
To quote Amosadvantage.com: (text bolding and color are my changes)
"NEW FOR 2022! An amazing 80 pages of images were added to post 1994 stamps picturing everything to make identification easier. Because of this addition,
two sections were removed from the U.S. Specialized catalogs and turned into separate publications: the Scott Stamp Values U.S. Specialized By Grade, 2022 and the Scott Identifier Of Definitive Stamp Issues, 2022, 1st Edition. By purchasing this bundle you will receive all three titles.
2022 Scott Specialized Catalogue of United States Stamps and Covers
The Scott Specialized Catalogue of United States Stamps and Covers is the essential reference work for collectors of United States postage stamps and postal history. The catalog also includes listings for postal stationery, revenue stamps, hunting permit (duck) stamps, essays, trial color, die and plate proofs, Confederate States of America, U.S. possessions and territories, and United Nations stamps.
Scott Identifier of Definitive Stamp Issues, 2022, 1st Edition
It's now even easier to identify stamps while using your Scott catalog. The Illustrated Identifier, formerly included near beginning of the Scott Specialized Catalogue of United States and Covers, is being published as a separate book for the first time.
The 2022 first edition of the Scott Identifier of Definitive Stamp Issues will be available for purchase later this year as a softcover book featuring 6-inch-by-9-inch pages in a two-column format.Scott Stamp Values U.S. Specialized by Grade, 2022
Here's some great news for collectors of graded U.S. stamps: The popular section in the Scott Specialized Catalogue of United States and Covers that provides market values in eight different grades for selected U.S. stamps is available again as a stand-alone publication.
The 2022 edition of Scott Stamp Values U.S. Specialized by Grade will be published later this year as a softcover book featuring 6-inch-by-9-inch pages in a single-column format."
------------------------------------
In other words, if you want to know the values of a stamp in any grade other than the Scott default of VF80, this 2022 catalog is useless; no more yellow bordered pages section. We will have to wait for Amos to get around to publishing the deleted sections.

Until then, we'll have to carry our old catalogs to shows and auctions.
