Archival Collections at Lyrasis

Welcome to the Lyrasis Arclight Demo Site

ArcLight is an open-source discovery and access application designed specifically for archival description and finding aids. It is built on the Blacklight framework (which itself is based on Ruby on Rails and Solr), and is intended to provide a modern, user-friendly interface for exploring archival collections.

What ArcLight Does

ArcLight allows users to:

  • Browse and search EAD (Encoded Archival Description) finding aids
  • Navigate hierarchical archival structures (collection > series > files > items)
  • View rich metadata and digital object links
  • Use facets (like subject, date, collection) to narrow search results
  • Export citation-friendly data
