2021	At the end of 2020 we activated a major site upgrade with simpler folder structure and index page. The search facility now searches general and maker-specific documents, but all maker-specific documents are now kept in the individual maker folders. The unknown maker clocks were revised. Over 400 patents were added, nearly 200 animations now added and hundreds of documents. After the upgrade we had over 20000 images from over 350 makers. New style headers for some folders with more external links to YouTube and websites (for example see Synchronome, English Clock Systems, Self Winding, No Key, Eureka, Lowne, and Siemens).
