The Official Traditional Catholic Directory has been issued in paperback since 1994 and only as an eBook since 2006, in the universal and free Adobe Acrobat PDF format. This format allows the Registry to revise the Directory monthly instead of annually. The Directory is free as of 2024, but if you wish to support the continued publication of the Directory, you may mail donations by cash, check, or (international) money order to the Confraternity of St. Michael, 21128 Baker Road, Castro Valley, CA 94546, USA. You can obtain a printed copy for your own personal use, if you wish, by printing out the PDF file. In accordance with copyright restrictions, the digital text cannot be copied.
