The modern landing page changes only navigation and context. Original scans, filenames, annotations, conversions, and historical mirrors remain unchanged.
Provenance
A distributed preservation project
According to the archive's original project account, Frank Calegari made photocopies from the books, Jim Borger scanned the copies, and William Stein supplied hardware, organized the files, and ran the web service.
Andrew Archibald, Antoine Chambert-Loir, and Vincent Maillot later contributed conversions and additional scans. The project established a stable, page-addressable web edition when access to these texts was substantially harder.
Primary collection
SGA volumes
Use page scans for citation-level navigation. PDF is usually the most convenient complete-volume format; DjVu and PostScript preserve alternate conversions.
