*"Professionals report substantial savings as a result of reading; average savings are nearly $600 per reading of journals, books and internal reports. These savings, relative to the cost of acquiring and using information, yield a return-on-investment ratio of about 10.2 to 1.

Note: This analysis does not include additional benefits derived from the library. No value estimates can be readily calculated for many potential measures. These include the value of creating metadata describing Mn/DOT publications. This metadata is added to WorldCat, which makes information created by Mn/DOT more accessible to transportation practitioners around the world. Also, it is difficult to estimate the "good will" value created by the loan of information resources to at least 179 organizations in 46 states, 5 Canadian provinces and 5 other countries in FY01, alone.
