This extension queries the DPLA each time you visit a Wikipedia article, using the article's title, redirects, and categories to find relevant items. If you click a link at the top of the article, it loads a series of links to the items.
The original code behind WikiDPLA was written at LibHack, a hackathon at the American Library Association's 2014 Midwinter Meeting in Philadelphia, PA.
