What this guide covers
Why public libraries are major genealogy hubs
Genealogy research has exploded since the 2010s, driven by DNA testing services (AncestryDNA, 23andMe) and the digitisation of vital records. Subscription services like Ancestry.com cost $39.99/month for the All Access subscription as of 2026; for many casual researchers, that price is prohibitive. Public libraries close the gap.
The Big Three library genealogy databases:
- Ancestry Library Edition (ALE) — a special version of Ancestry.com licensed to libraries by ProQuest. ALE includes most of Ancestry's databases: U.S. census 1790-1950, vital records, military records, immigration records, and more. ALE is in-library access only (no remote login).
- HeritageQuest Online — also from ProQuest, includes U.S. census 1790-1950, the PERSI periodicals index, Revolutionary War pension files, and more. Most libraries make HeritageQuest available remotely with a library card login.
- FamilySearch.org — free to all users worldwide, operated by The Church of Jesus Christ of Latter-day Saints. Massive vital records collection; free FamilySearch accounts let you save your family tree.
The Library of Congress, the National Archives, and major U.S. public library systems also offer free access to specialised genealogy resources. The Allen County Public Library Genealogy Center (Fort Wayne, IN) is the largest free genealogy collection in the U.S.

Where to start your genealogy research
Genealogy research can quickly become overwhelming. Here is the standard 'reverse pedigree' approach used by most genealogy reference librarians:
- Document yourself. Birth date, place. Marriage date, place (if applicable). Children, if any.
- Document your parents. Birth, marriage, death (if applicable).
- Document your grandparents. All four sets of grandparents — birth, marriage, death.
- Use census records to confirm and extend. The 1950 census (released April 1, 2022) is the most recent. Searching backward through 1940, 1930, 1920, 1910, 1900, 1880 censuses lets you trace family back to the late 19th century. Earlier censuses (1850-1880) name only the head of household before 1850.
- Look for vital records. Birth, marriage, and death certificates from state vital records offices. Libraries help you order these.
- Check immigration records. Ellis Island arrivals (Castle Garden, 1892-1924), naturalisation records, passenger lists.
- Connect with cousins. Use FamilySearch tree, Ancestry public trees, MyHeritage, and DNA testing services to find relatives doing similar research.
Frequently asked questions
Is Ancestry Library Edition the same as Ancestry.com?
Mostly yes. Ancestry Library Edition (ALE) is licensed to libraries and includes all of Ancestry's main databases: U.S. census, vital records, military, immigration. The differences: (1) ALE is in-library access only (no remote login), (2) ALE does not include the AncestryDNA matching feature, (3) ALE does not let you save your family tree (use a personal Ancestry account or FamilySearch for that).
Why does Ancestry Library Edition only work at the library?
ProQuest licenses ALE to libraries with strict in-building access controls. The license is significantly less expensive than the consumer Ancestry.com subscription, but the trade-off is no remote access. Some library systems let cardholders use ALE remotely during specific 'remote access events'.
Can I make my family tree on a library computer?
On Ancestry Library Edition, you cannot save a personal tree (the library uses an institutional account). Use FamilySearch.org instead — it is free, works on any computer including library computers, and lets you save and edit your tree.
How far back can I trace my family in U.S. records?
U.S. federal census records go back to 1790; many state and county records go further. For most U.S. families, you can trace back to the early 1800s with persistence. Tracing further depends on whether the family appears in colonial records (which exist for some New England, Mid-Atlantic, and Virginia families) or whether the immigrant ancestor's home country has accessible records.
What about African-American genealogy?
African-American genealogy requires specialised approaches. Pre-1865 records of enslaved people are often missing or scattered (slave schedules, plantation records, Freedmen's Bureau records). Resources: National Archives Freedmen's Bureau records, Ancestry's African-American collections, FamilySearch's African-American records, and the Afro-American Historical and Genealogical Society. Libraries with strong African-American genealogy collections include Detroit Public Library Burton Historical Collection, Memphis Public Libraries Memphis & Shelby County Room, and Louisville's Western Branch Black History Collection.
Are DNA tests reliable for genealogy?
DNA tests are useful but require interpretation. AncestryDNA, 23andMe, and others have large databases that find DNA matches with relatives. Ethnicity estimates are less reliable than match lists. Library genealogy reference librarians can help you interpret DNA matches and connect them to documented family history.
How do I get a death certificate?
Death certificates are issued by state vital records offices, not federal. Each state has its own procedure and fee ($15-25 typical). Libraries help you identify the right office and fill out the request form. The CDC's National Center for Health Statistics maintains a directory of state vital records offices at cdc.gov/nchs/w2w.
