“It is nearly 18 years since I began building iron bridges,
and the Elgin and Dixon bridges are the only ones that
have fallen, and no loss of life except at Dixon.
Can as much be said of any other plan?”
- Lucius E. Truesdell, May, 1873

The Cost of Lock-In
● Proprietary formats in
government specifications
● Licensing creates
obsolescence
● High costs restrict access
to smaller agencies
