Design Challenge
The Library of Congress' marquee digital property is, a website that on average has 7 million unique visitors a month, and over 2.7 million collection items online in a variety of formats including image, audio, video, text, PDF, and data sets.

We attract users of all kinds, but the Library's largest primary groups include: researchers, historians, genealogists, librarians, artists, K-12 educators, journalists, and students.

After orienting yourself to the Library of Congress and, what data visualizations would you and/or these primary user groups like to see on to better understand the Library's collections?

Is there an interactive data visualization that would be useful in targeting or finding items that are of interest? This can be either across the breadth of the collections or focused on a format, date range, location, subject, or more defined collection (part of). Would this also include the ability to create datasets using the visualization for download?

If not a data visualization with interactive features, what features would you suggest to attract users and help them with the orientation and navigation of the many diverse collections at the Library? What features would you suggest to promote the creative use of collection items? Do you have an idea about a better interface for the search/exploration of our materials?
