Errata & Content Updates

This page records substantive corrections and content updates made to the Virtual Textbook since it moved to its new home — places where a chemical error was fixed or a topic was modernized, together with the source of the change. Presentation-only and site-wide changes (migration, accessibility, rebuilt viewers) are listed separately in the About this Textbook & Changelog page.

The chemistry is the work of the late William Reusch; these entries note where the maintainers have revised it, and who advised the change.
