Long term data preservation is important from several points view like

History

• unique proton-antiproton collision
• top quark discovery

Education

• exercise on real data

Science

• The data are still used : “Combination of the CDF and D0 effective leptonic electroweak mixing angles and indirect measurement of the W mass” (http://tevewwg.fnal.gov/wz/sw2eff/)
