# Downloaded-source metadata and access notes

These files were downloaded from URLs listed in `data-center-environmental-bibliography.md` on 2026-07-29. They are included for research convenience; the linked publisher or agency page remains the authoritative source. Copyright, licensing, and access terms vary by item.

The collection prioritizes open PDFs and primary planning/government documents. Several DOI links in the bibliography resolve to publisher landing pages rather than openly downloadable PDFs, and some hosts block automated PDF retrieval. The bibliography retains those citations and URLs.
