Hi Mark,

We are also interested in providing hierarchical browsing for some of our
collections, though our reasons and goals may be different from yours. We
have very large book collections and want to offer users a way to navigate
beyond searching/filtering or "browse all." Our idea is to use the call
numbers for the books, which map to LC class and subclass, which is a
hierarchy. We haven't done this yet, so I can't show you an example, but I
wonder if it's something you can use for your project.

So far, we do allow users to "find similar" titles by clicking on LCSH
subjects for a given book:

Not sure if this type of navigation might be useful to you.
