Horology, the Index is a major resource containing thousands of horological based links. It is very outdated and is now a project for I.A.C to rebuild. Rebuilding will involve checking and correcting existing links and building in new links. This is a great project that you can spend a few minutes or a few hours working at your computer to help revive a valuable but now dated resource. Project leader Sam Kirk can fill in any details you may need to get started. Get involved. The NAWCC relies on the efforts of it's members to bring you these valuable resources.
