Interesting idea if done on a screen-by-screen basis. That is, you simply don't display to the user those that aren't available. I've thought about this same strategy for a "full-text" filter. That is, you bring back all the results, but if the user only wants items that have full-text available, you filter out those that don't as you build the screen display. This of course has a hit on response time, but with APIs that allow multiple-item lookups, it is at least not as bad as it could be. Roy
