[Sigia-l] Product Indexes - Good Examples?

[Peter Merholz]

Hey all--

I'm researching product indexes, and am struck by how few take advantage of
being on the web.

I'm familiar with the very good example at PeopleSoft.com
http://www.peoplesoft.com/corp/en/indices/prod_index.asp

But I'm hoping for something that goes beyond simple alphabetizing to
include other elements.

I'm thinking that it would be nice to have an index in a table, with columns
perhaps being "product line" or "free trial" or whatever. Ideally you'd be
able to sort on those columns, but at the least you could visually scan for
things in those columns.
(To some degree, I want to imbue an index with a touch of facet-y goodness.)

However, in searching "Products A-Z" or "Product Index" on Google, I'm
getting the same old alphabetical lists.

Thoughts? Pointers?
