How to check this yourself

Each copy above is identified by the SHA-256 of its extracted text, shown beside it, and the diffs are plain unified diffs. To verify a quotation, compare it against the page itself or against the Internet Archive's copies, which are independent of this project.

Complete captures are held offline rather than mirrored here, so this page shows diffs and excerpts. If a quotation is ever disputed, the full copy can be produced. Ask.
