This November brings the 24th edition of the 2018 Scott Classic Catalogue. There are more than 17,000 changes in catalog values. I have trouble getting excited about trying to enumerate these so I'll just point you athttps://www.linns.com/news/us-stamps-postal-history/2017/november/2018-scott-classic-specialized-catalog-available.html
It is worth noting that there are price decreases as well as increases. And there are valuations for some stamps in various conditions and formats for the first time.
In terms of editorial content, many notes and footnotes have been reviewed for accuracy. There are 3 major numbers and almost 230 minor varieties added for New Zealand. Other additions include Azerbaijan, Fiume, Hejaz, and Saudi Arabia. And there are improved scans for some stamps.
The cost is $174.99; $154.99 direct from Amos Advantage.
