There were 22 bills introduced during or just before Clinton's impeachment (9/1/1998 to 12/19/1998) that were signed by the President.  There are many more bills that were introduced earlier but which were still moving though Congress during this period (probably at least a hundred).  And that does not even count bills considered by Congress that were not signed by the President for whatever reason.
