Because the Independent Catholic movement is so decentralized and its communities are not always very stable, it is difficult to keep tabs on everyone. Most directories fall out of date rather quickly as people move, join new jurisdictions, or leave the movement altogether. This site does not include a directory of its own, but here are links to a few other directories on the web. Most of the sites are somewhat out of date, but they are still largely accurate. The best and most up-to-date is probably the Independent Sacramental Movement page maintained by Fr. Will Meyers.
See also Church Links for examples of a few specific communities I’m familiar with.
