What Makes an Exhibition
Exhibition pages are built when a case has enough original documentation in the archive to reconstruct it from first-hand records rather than secondary accounts. Each exhibition draws on government investigation files, field researcher reports, newsletter coverage, and witness statements held in the NHI Archive.
For the full case database (1,030 cases), see the Case Files. Cases with exhibition pages are marked with a brass badge in the listing. For declassified government document collections, see the Government Documents.
