  9. What are the typical collaborative search tasks? • Watched over someone’s shoulder as he/she searched the Web, and suggested alternate query terms. • E-mailed someone links to share the results of a Web search. • E-mailed someone a textual summary to share the results of a Web search. • Called someone on the phone to tell them about the results of a Web search.
