From August 12-October 11, contributors from Stanford University, Duke University, Indiana University, University of Michigan, and Princeton University focused efforts on continuing work on ArcLight, a discovery platform for archives based on Blacklight. During this nine-week period, work included:


  • A substantial redesign of collection and component displays, search results, context trees, and online content
  • A rewritten indexing pipeline for loading data into Solr, built using Traject and addressing performance concerns
  • A new group-by-collection feature for search results
  • Many changes to improve usability and accessibility in ArcLight, with some changes made upstream to Blacklight
  • Better support for request management integration, including integration with Aeon through either externally-hosted EAD files or Aeon’s external request endpoint
  • Programmatically generated download links, e.g. for PDF or EAD versions of finding aids
  • Improvements to relevance ranking


These changes have been released as ArcLight 0.3.0, now available both on Github and from Rubygems.


Our final 37-minute demo video can be seen on YouTube: – and all past demos from the work cycle are available as well. Our shared demo instance of ArcLight has also been updated.
