A photographic history with cited opening dates, collection history and individually credited images. Historic views, later photographs and illustrations are dated separately. This is a selected collection, not an exhaustive inventory.

Includes catalog records, credits, acquired OCR where available and a SQLite FTS5 database. Images with relative filenames are bundled. Newly added photographs at https://silentgroundscollective-uyjaw.wordpress.com are hosted in the SGC media library and require an internet connection; they are not embedded in this ZIP. Complete repository PDFs and modern external articles are linked, not included. Coverage and missing records are described in each collection’s scope and individual item notes.

RESEARCH DATABASE
items stores the catalog; search_fts indexes source text. Example: SELECT id,title FROM search_fts WHERE search_fts MATCH 'history';
