Current departmental website policy is to keep only reports from the last five years on the MaineDOT pages. Many of the older and current reports are in the National Transportation Library. If anyone is looking for something not available on either site, they can contact the research unit - http://www.maine.gov/mdot/tr/, or the MaineDOT Library - http://www.maine.gov/mdot/library/.
The WisDOT Library is a participant in Recollection Wisconsin, a cooperative digital effort which provides Wisconsin residents and audiences worldwide with free access to a growing set of historical resources from the collections of libraries, archives, museums and historical societies across the state. Please visit the WisDOT Library's digital collections.
