I think it's in the Mudcat resources, but here it is anyway.As for navigating it, it depends what you're looking for. It seems a bit better organised that it used to be, but the files are basically just text. I usually go into the bit I want (e.g. Scarce Songs 1) by cursoring down and clicking on the Bluey. Then I use the Edit/Find (on this page) feature of the browser to do a keyword search (try Glasgow. If you keep doing [Find Next], you eventually get there.
With patience, it's not usually too difficult to find what you want, and it's really a massive resource.
Cheers!
