I've extracted the editorial content from the master volumes, and I'm now building a separate index page for each of the volumes we've created, including the editorial stuff. On the other listings pages, volume numbers are now links to the volume pages. This answers (I think) the last of HT's requirements for the new site, other than a redesign.

I've also tested Apache Tika with the old volume PDFs, and the results are very promising; I think we may be able to process them to ugly XHTML, which eXist could then index, and provide people with search capabilities and linking out to the specific page in which the hit is found.
