From the The Dallas Morning News:
George W. Bush’s presidential library is taking shape in early designs, evolving from separate buildings at SMU into a single, multi-story complex with a policy institute nearly two-thirds bigger than first proposed.
The overall structure has grown to an estimated 207,000 square feet – akin to an average Wal-Mart Super Center – making it more than twice as large as his father’s, the George Bush Presidential Library and Museum at Texas A&M University.
