The WSDOT Library and affiliate libraries at the Materials Laboratory and Washington State Ferries exist primarily to serve the information needs of agency employees and WSDOT contractors.  We welcome inquiries from the general public and will answer them as time permits.

In addition to providing information services within WSDOT, professional library staff are involved in a cooperative effort with transportation librarians nationwide to coordinate the development of a national transportation knowledge network. 

Within the agency, WSDOT librarians work with other agency staff to develop procedures which utilize controlled vocabularies to catalog electronic documents. 

The WSDOT Library holdings are included in the Washington State Library catalog.  

Public Access

We are open to the general public for materials to be used in-house.  If you plan to visit, we recommend that you contact us and make an appointment. Certain materials may be borrowed through interlibrary loan.

Requests for agency records - not materials in the library collections - are referred to the Records Management Office.
