How to Use This Archive

The AOH Online Archive is a public, searchable catalog of primary and secondary sources on the Ancient Order of Hibernians (AOH) and the Ladies Ancient Order of Hibernians (LAOH). Its job is to help you discover that a collection or item exists and where it is held, then send you to the library, archive, university, or historical society that actually holds it.

Finding material

Browse by State, Repository, Material Type, Era, or Organization (AOH / LAOH). Each browse page shows how many entries it contains.
Search by keyword — a collection name, repository, place, or subject — using the search box on the home page or in the navigation.
Filter a set of results by combining any of the browse categories at once. Filtered result pages are ordinary web addresses, so you can bookmark or share a search exactly as you ran it.

On each entry page

The holding repository, its city and state, and a description of the material where one is available.
A prominent link to view the finding aid at the holding institution — follow it to see the material’s own catalog record and to learn how to request access.
A copy-ready Chicago-style citation, built from a stable accession number (for example AOH-0042), so you can cite the entry itself in your own research and footnotes.
Where we have kept one, a preserved archived snapshot of the repository’s finding-aid link, in case that link ever changes.

What you won’t find here

So there is no confusion about what this site is:

Not the documents themselves. This is a guide to where records live, not a digital library. We link out to the holding institutions; we do not host scans, photographs, or PDFs of the material itself. To view or use the original records, follow the link to the repository and contact them directly.
Not a member-name index. This is a collection-level finding guide, not a genealogy lookup — it does not list individual members by name. It can, however, point you toward collections that may themselves contain membership rolls or similar records, held at the repository named on that entry.
No login, and nothing members-only. Everything in this catalog is public. There is no account to create and nothing restricted to sign in for.

Help us complete the record

This catalog grows through the people who use it. If you know of an AOH- or LAOH-related collection that isn’t listed here, or you’ve spotted an error in an entry, please tell us — see Contribute, linked from every entry page and in the main menu. Every submission is reviewed by the National Archivist before anything is added or changed.
