A correction log should explain what changed, not only that a page was edited

A Library Rules note on correction logs for pages that readers may reuse.

A raw edit history can show that a page changed, but it often does not tell readers whether the meaning changed. For reusable notes, I think a correction log needs date, old claim, new claim, reason, and source checked. That is especially important when a changed sentence affects browser support, eligibility, policy wording, or a deadline. Grammar fixes can stay quiet; decision-changing edits should be visible.
