Knowledge library

Documents with their evidence attached.

The library will unite manuals, proceedings, newsletters, scans, technical notes, and searchable transcripts without separating an artifact from its source history.

Attachments & reading room

Proceedings, newsletters, program-library records, and community ephemera show how the culture actually worked. Files open at the preserving institution; dates, custodians, and formats stay visible.
