Sorcha, It is clear I don't know enough to find a complete workaround for this problem but there may be certain other "backdoor routes" to bits here I can find.

Many of the quicklinks are given like this one:

<OPTION VALUE="http://www.mudcat.org/product_request/index.cfm">Product Request>

We know you can't find www.mudcat.org but we know that IP address. In many cases, probably you can do it yourself. Just try the link, let it fail and swap "www.mudcat.org" for "207.103.108.105" And give that to your browser.
