Wikipedia should avoid breaking links wherever possible. However, its community of alternate inclusionists and deletionists like to use the delete links quite a bit. Some interesting pages, collections, and fora are from time to time deleted, moved and deleted, transwikied to other sites that then disappear from the 'net, and otherwise hidden (often unintentionally).
This is a collection of things that have at some point been on Wikipedia, at some point been deleted or threatened with deletion, which I would like to preserve a link to. If you feel compelled by virtuous zeal to delete anything linked below, please let me know.
