Courtesy of Joe Offer and Max, I've been given the opportunity to go through the whole Mudcat Links section with a view to checking all the links and editing them where necessary. Where a link is out-of-date, the process I've used is as follows:
1. Where the website exists under a more modern URL, I've simply updated the URL.
2. Where the website is defunct, I've traced the last useable record of the site in the Internet Archive's "Wayback Machine" and added the Wayback URL. The original URL has not been edited out.
3. Where the website has gone, with no evidence of any traceable pages from the past, I've deleted the link. There are only a handful of these.
I shall be keeping a regular eye on the Links section to make sure it's kept up-to-date. I hope to add some useful ones where I've come across them in my "links" trawling through the web - and suggestions from 'Catters for alterations and additions are more than welcome.
