Congressional Data Challenge

Get Data and Details

The submission period is closed. We will announce the winners in June 2018.

A variety of legislative data is available on the website (for some examples, see our LC for Robots page). We are sponsoring this legislative data challenge to advance the discovery, use, and exploration of the collection of legislative information the Library offers to the nation and the world through the website

What are we looking for?

We’d like to see creative use of technology to analyze digital Congressional information from This could take the form of interactive visualizations, mobile or desktop applications, a website, or other digital creation.

To get you thinking, we offer a few example projects:

  • a visualization of how the legislative process works using legislative data
  • tools that could be embedded on Congressional and public websites
  • legislative matching service, to identify Members with similar legislative interests
  • tools to improve accessibility of legislative data
  • a tool that, based on bill text, identifies Members of Congress with legislative interests that are similar to the user’s, or to the legislative interests of other Members of Congress

It might help you to look at the Chronicling America data challenge winners for inspiration in how innovators of all ages have looked at data in a new way.


The Library of Congress will award $5,000 for first prize and $1,000 for the best high-school project. Honorable mentions may be awarded for

  • best tracking of legislative status
  • best data visualization
  • best data mashup


Thanks to all of those who helped shape this contest, especially NEH following its successful Chronicling America Data challenge; the United States Government Publishing Office’s Federal Digital System / govinfo team; and the Internet Education Foundation, coordinator of the Congressional App Challenge.
