Forum:How should we deal with link rot?

The 8 free e-books (of Human Nature, etc.) that used to be at http://www.bbc.co.uk/doctorwho/classic/ebooks/ disappeared in a site reorganization some time this year. On each of the 8 novels' articles here, we've got a link to the no-longer-existing page.

You can still find them all at the Wayback Machine (http://wayback.archive.org/web/*/http://www.bbc.co.uk/doctorwho/classic/ebooks/). The online and printable versions seem to be accessible at any snapshot from 2005 to 2010. To see all the images, and to get the PDF, PDB, LIT, and Mobi versions, you may have to look through a few different snapshots.

I don't know what this wiki's policy is on this. Should we replace the links in the articles to Wayback archived versions, remove them, or replace them with a note that they used to be available at (URL in plain text rather than as a link) but no longer are? --70.36.140.19 07:03, September 23, 2011 (UTC)
