1995-1996 Is currently the least productive two-year Congressional session on record, dating back to 1947 when the U.S. House Clerk’s Office first began keeping such records. The 104th Congress passed 333 bills in total.
2011-2012 Will become the new least productive two-year Congressional session on record, barring a number of miracles during the final days of the 112th Congress. Our sitting senators and representatives would need to send at least 115 more bills to the desk of President Obama to avoid becoming the least productive Congress in decades. Currently, they’re at 219 for the session. source
