​Transparency in government

We’re committed to being transparent in our operations and activities.

OpenBook Wisconsin provides easy access to state of Wisconsin expenditures, including those for the Wisconsin Department of Transportation.

The OpenBook Wisconsin website includes more than 25 million entries showing the payments made for purchasing goods or services, travel and vendor payments for state agencies, the legislature, the courts and the University of Wisconsin System. Data is available about expenditures made by state government from fiscal year 2008 through the most current month.
