Duh - seek and ye shall find. Found my own answer in one of the FAQ's - posted 1/13/03.

***Changes to Advanced Search***

As announced last week, we are removing two of the tabs within the Advanced Search area. The Item Number search tab and the Completed Items search tab will both be removed. These search capabilities are still available within other tabs of Advanced Search.

The Completed Items search functionality has been integrated into the Advanced Search page. This will enhance a member's ability to search for completed items combined with many of the search filters available on the Advanced Search page. To search for completed items, check the "Completed Items only" checkbox.
