Abstract: A method, system, and product are disclosed for displaying directory information and dynamically updated contact information for one or more people in response to a directory search. A user submits a query criteria when the directory search is requested. A search of the directory information is first executed utilizing the query criteria to return a first result set. A search of dynamically updated contact information is then executed using the first result set to produce a second result set. A final result of the directory search request is then produced by coalescing the first and second result sets. This final result includes both directory information and dynamically updated contact information for each person whose name was included in the final result.
