A complete RSS feed for the official Berkshire Hathaway shareholder-letter archive.
The feed contains all 48 linked annual letters from 1977 through 2024. The publisher provides full HTML for 1977 through 1997 and PDF files from 1998 onward. The 1998 through 2003 archive links are short Adobe notices, so the feed points to their official PDF targets while retaining the archive URLs as stable GUIDs. Feed items omit pubDate because the archive gives a report year, not an exact publication date.
refresh.ts updates the cache daily. main.ts also refreshes a cache older than six hours when requested and serves the last good copy if the publisher is temporarily unavailable.
