City directories: the pre-internet phone book that maps who lived where
Before the phone book, American cities published annual directories listing every adult by name, address, and occupation — and many printed a street-by-street section you can read like a census of your block. How to use them, and where to find them free.

The census fires once a decade and the deed only records a sale, so there's a question both leave unanswered: who lived in the house in all the other years? The answer, for roughly a century of American life, is the city directory — the annual book that listed nearly every adult in town by name, with their address and occupation. It is the most underused source in house history, and for tracking the people in a house year by year, nothing else comes close.
What a city directory is
From the early 1800s into the mid-20th century — when the telephone book finally replaced them — American cities published a directory every year (sometimes every two). A commercial publisher (Polk, Boyd's, McElroy's, Gopsill's, Might's, Henderson's, and many local firms) sent canvassers door to door and printed an alphabetical list of the city's adult residents: name, home address, occupation, and often employer. A widow was usually noted as such; a resident's race was sometimes marked (a painful but real research aid in segregated cities); boarders and roomers were frequently listed too.
Because they came out annually, directories fill the long gaps the once-a-decade census leaves — and they often caught people who moved between census counts and vanished from the federal record entirely.
The secret weapon: the street directory
Here's the part most people miss. Many city directories included a second section organized by street and house number — a "householders'" or "street" directory — so you can look up your address and read off who lived there that year, then walk the same address forward through edition after edition. Done across twenty or thirty years, this builds something close to a year-by-year occupancy record of your house — the closest thing to a continuous tenant list that exists for most American homes.
Not every city printed the street section every year, but where it exists it's gold: a deed names the owner, but the street directory names whoever actually answered the door.
How to read them well
A few habits make directories sing:
- Track a name across editions to find exactly when a family moved in and moved out — the years they first appear and last appear bracket their tenancy.
- Use the street section (where it exists) to see everyone at the address over time, not just one family.
- Read the occupation — it dates and humanizes a resident, and it helps you tell two people of the same name apart.
- Cross-check against the census. A name in the 1915 directory plus the 1910 and 1920 censuses confirms a household and resolves spelling drift.
- Mind the lag. Canvassing happened months before publication, so a "1920" directory reflects late-1919 residence — and a person who died early in the year may still appear.
Where to find them free
The single biggest free trove is the Internet Archive (archive.org), which has digitized thousands of city directories, full-text searchable. Beyond that, your city's public-library local-history room almost certainly holds the local run (often digitized — the Denver, Boston, Los Angeles, Toronto, and Vancouver libraries all have strong directory collections), and state libraries and historical societies hold others. HathiTrust and FamilySearch carry many more. Coverage is uneven year to year, so check more than one repository.
The honest limits
Directories listed adults, usually heads of household and working residents — so children, and sometimes wives, may not appear under their own names. Canvassers missed people and misspelled others, and the poorest and most transient residents were undercounted. The street-directory section isn't in every edition. And the OCR on digitized directories is imperfect, so search variant spellings. None of this diminishes their value — it just means you read them, like every source, as the human-made artifact they are.
How Plot uses the people record
Plot's people resolver stitches the names tied to an address — from deeds, the census, and the press — into coherent individuals and family lines, the same work a researcher does by hand with directories open on the desk. Where the directory is the source that catches a between-census tenant or resolves a name, it's part of the same goal: turning scattered name fragments into the real people who lived in a house. Pull the directories yourself with Plot's assembled history open beside you, and the years between the censuses fill in.
