Ocean Passages for the World is kept up to date by supplements, each new supplement cancelling the previous one. In addition important corrections which cannot await the next supplement are published in Section IV of the weekly editions of Admiralty Notices to Mariners. A list of such corrections and notices in force is published in the last weekly edition for each month. Those still in force at the end of the year are reprinted in the Annual Summary of Admiralty Notices to Mariners.
