One of MTKN's major initiatives was the creation of an online "union catalog" of transportation materials in the Midwest region and nationally in cooperation with the OCLC Online Computer Library Center. This resource makes finding pertinent reports and documented transportation research much quicker and more efficient. This database is called The Transportation Libraries Catalog (TLCat). The National Transportation Library (NTL) spearheaded this effort.
