Well, we don't use a database at all, it really is just indexing. An index, after all, can "act" like a database for many purposes. Where an index falls down is in high transaction rate applications, but that hasn't so far been the problem we need to solve. > We are also thinking about how to store the status information > (available or checked out).

Do we store the info in a seperate DB, etc. I would say status information, that is likely to change on a regular basis, really does belong in a database rather than an index (reference comment above). But that's just my opinion. Roy
