How to check this yourself

The excerpts and plain unified diffs above show the text this project held and how it changed. 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.
