Category:Pages with broken external links

Pages with links to external pages that don't exist, marked with the  tag.

Ideally, the broken links should be replaced with working links to the same content - either from copies stored in the Internet Archive's "Wayback Machine" or on completely different websites. Only if there are no alternate links anywhere should the broken links be removed instead of being replaced.

Please do not delete this category if it is empty - we might need it again later.
