Description
Have you ever wondered how the popular CWS Worldwide Supplements come together? These essential pages aren’t assembled by automation or outsourced to a third party—they’re the result of hundreds of dedicated hours by our in-house team at Collectors Supply House (CWS). Each year, our staff combs through international websites, compiling the most complete and up-to-date listings of stamps issued around the globe.
Once our researchers have gathered this information, our creative team takes over—designing and formatting each supplement into clear, country-by-country layouts that enhance the beauty and organization of your collection. The result? A collector-favourite supplement, made in Canada, and trusted for decades.
In 2021, we took a bold step to “catch up” by expanding coverage across 2019, 2020, and 2021—nearly tripling the size to 430 pages and over 100 countries. This upgrade answered the call of collectors looking for a more comprehensive product. While rising paper costs led to a price adjustment, the overwhelming response confirmed we were on the right track.
Due to the continued demand for the enhanced version—and a noticeable decline in interest in the basic edition—we are now offering only the fully enhanced World Wide Supplement as of 2023. The 2022 expanded version, for example, includes 474 pages across 153 countries, a remarkable 228% increase over the base model.
Supplements are available in three popular page formats to suit your album:
• 8.5 × 11 three-ring
• 9 × 12 three-ring
• 9 × 12 two-post
