I had a look just now. Ross Campbell's link takes you to the original page or a copy of it. The search there still works but the links to the scanned images are broken. Presumably this page is to be retired?

Q's link looks fine to me. Click on "Home" at the top of the page and you get to the new home page:

http://ballads.bodleian.ox.ac.uk/

As Steve Gardham says, the new page looks fine; just different and in some ways better. I like the Theme menu on the left as I sometimes browse the site for songs on a specific theme which I either rewrite to reflect present times or just write a tune to fit the words. If you're looking for a specific song, there is a search box at the top of the page or there is a link to an advanced search page where you can conduct a more specific search.

I've bookmarked it and will probably delete the link to the old page as it's clearly no longer much use.
