This link no longer works. What should I use instead?

A website, consisting of two user interface pages, a crawler, and a database.

Main service (Page 1): Users can enter URLs that no longer work. For a small number of them, the website presents one or more suggestions for replacement URLs, maybe with comments. (This functionality could be exported as a machine-accessible service as well.)

These replacement URLs are found by two means: automatically and manually.

Automatically (Crawler + Database): A search engine that notices when different places (e.g., blogs) refer to the same URL at one point in time, and when, at a later time, some of those references have changed. (The surrounding text is still the same, but the URL has changed). If the search engine detects such a case, the second URL is a potential replacement for the first.

Manually (Page 2): A place where the human owner of the resource or a knowledgable, identified person can suggest a replacement for an URL. (E.g., "I have lost access to this subtree. The new, updated version is _here_."

[contracts] used it as a sample nonexistant website, prompting me to search for an excuse to create it. [jutta, Nov 13 2004]

http://www.archive.org Always a good fall-back, but I don't want a copy of the original document; I want the a new address of the live, maintained, document. [jutta, Nov 13 2004]

       What about a modified form of the second means, where helpful (but less authoritative) people can point out other possibilities?

       [jutta] said //a knowledgable, identified person can suggest a replacement// and [detly] said that helpful //people can point out other possibilities//

Sounds like you're both describing a sort of 'Linkipedia'[+]

       //create a monstrous library db//
It may not be indexed precisely for the purpose of this idea, but I think said database already exists. Google.
  

       My idea "Link Rover" in this category was a different approach to this same problem: capture the target page text at the time the webmaster creates the link initially, so that later when the link breaks a replacement can be found in an automated fashion.   

       Perhaps this idea, implemented as a web service instead of a web site, would be the back-end of a client-server version of Link Rover.

       I think your Rover and my Emporium would augment each other well - one looks at context, the other at content. (For the prototype, we can use archive.org as your monstrous database.)
