Contact

The fastest way to reach us is by email: [email protected]. We read every message and review every correction request against our sources before making a change.

Reporting a Factual Correction

If you've spotted a date, figure, or fact that looks wrong, tell us which page it's on and what you believe the correct information is, ideally with a source we can check it against. We compare every correction request to a named, publicly available reference before editing a page; see How We Source for what counts as a reference here. Confirmed corrections are made directly to the page, and its last-updated date is refreshed to reflect the change.

General Questions

If you're a student or teacher with a question about how a timeline was researched, a reader curious about a gap in the archive, or just someone who wants to flag a topic you'd like to see covered, the same email address reaches us. We can't promise a reply to every message, but we do read all of them, and reader suggestions have shaped which timelines get added next.

Using This Site's Content

History Timelines is built to be cited freely: every page includes a ready citation block in APA, MLA, and Chicago formats for exactly that purpose, and no permission is needed to cite a timeline in schoolwork, an article, or a research project the way you'd cite any other reference work. If you're looking to do something beyond citation, such as reproducing a full page, using our images, or a media inquiry, email us with the details and we'll get back to you.

Response Times

This is a small, actively maintained reference site rather than a large newsroom, so please allow a few weeks for a response, longer for complex correction requests that need to be checked against multiple sources. Time-sensitive corrections on pages covering people or situations still in the news are prioritized.

For Teachers and Researchers

If you're building a lesson plan, a research bibliography, or a classroom resource list around one of our timelines, you don't need to ask permission first: every page is free to cite, and the citation block at the bottom of each timeline is built for exactly that use. If you'd like us to add a topic your class is covering and we don't yet have it, tell us; reader and educator suggestions are one of the main ways we decide what to research and add next. We can't guarantee a timeline will be added or when, but we do read and weigh every request.

Media and Permissions Requests

Journalists, editors, or site owners looking to quote from a timeline, request an interview, or discuss a partnership can use the same email address. Please include a brief description of what you're working on and your deadline, if any, so we can prioritize accordingly.
