Guide to Finding Old Business Records

What businesses operated in your neighborhood fifty, seventy-five, or a hundred years ago? The grocery where your grandparents shopped, the drugstore with the soda fountain, the factory that employed half the town: these businesses shaped daily life, but most never kept an archive of their own. Their traces survive instead in other people's records: directories, newspapers, insurance maps, government filings, credit reports, and the memories of customers. This guide explains which record answers which question, who holds it, and how to search it.

Why Research Old Businesses?

Most people arrive with one of three goals: identifying what occupied a building (often because they own or rent it now), tracing a family business, or documenting a commercial street for a local history project. Each goal starts in a different place. For a building, work by address in directories and Sanborn maps. For a family business, work by owner's name in directories, the census, and newspapers. For a whole street, work block by block through one directory year at a time and build a table of occupants.

City Directories: Your Primary Resource

City directories were published most years in most American towns from the mid-1800s into the mid-to-late 1900s. They list businesses three ways: alphabetically by name, in a classified section by type ("Grocers," "Undertakers," "Auto Repairing"), and, in many 20th-century editions, in a street section that lists every address in order with its occupant. The street section answers "what was at 412 Main in 1931?" without knowing any name.

Finding City Directories

Scanned directories are free on the Internet Archive and in FamilySearch's digital book collection, and many state and big-city libraries have put their local runs online. Ancestry's large U.S. city directory collection is free on library computers through Ancestry Library Edition at many public libraries. Your library's local-history room almost certainly holds the local run in print or on microfilm. Our guide to old city directories lists the main free collections and how to search them.

Using City Directories Effectively

Copy the occupant of your address from every edition you can find, then fill gaps from the alphabetical section. Read the abbreviations key at the front: "propr" means proprietor, "mfr" manufacturer, "mgr" manager, and an entry such as "Kowalski Frank (Kowalski Bros) h 412 Elm" tells you he was a partner in the firm. Directory information was usually gathered months before publication, so a 1925 edition mostly reflects 1924. Display ads in the classified section often name the owner and describe what the business sold.

Newspaper Research

Newspapers record a business's life in public: the grand-opening ad, years of display ads, "under new management" notices, fires, lawsuits, the going-out-of-business sale, and the owner's obituary. Legal notices are especially useful because the law required them: notices of incorporation or dissolution, partnership dissolutions, bankruptcy filings, sheriff's sales, and fictitious-name filings were printed in many states.

Accessing Historical Newspapers

Free sources include the Library of Congress's Chronicling America, Google News Archive, and many state newspaper portals; your public library may offer free remote access to subscription archives such as Newspapers.com or NewspaperArchive. See our list of free historical newspaper archives. Search the business name, the owner's name, and the address in several forms ("412 Main," "412 Main St."). OCR on old newsprint is imperfect, so try misspellings and browse the pages around a hit, where related ads often sit.

Fire Insurance Maps

Sanborn fire-insurance maps, made from the 1860s into the 20th century and revised every few years, show each building's footprint, height, and construction, and label its use: "Grocery," "Saloon," "Auto Garage," "Drugs." Larger businesses such as mills, lumberyards, and breweries are often labeled by name. Comparing editions shows when a dwelling became a store or a livery stable became a garage.

Accessing Sanborn Maps

The Library of Congress has put a large share of its Sanborn holdings online free, and many state libraries and universities host their own state's maps. Colors mark construction (yellow for wood frame, pink for brick, blue for stone), and abbreviations such as "D" (dwelling) and "S" (store) mark use. Our guide to reading Sanborn fire insurance maps decodes the symbols and explains how to date a building from successive editions.

Business Permits and Licenses

Cities and counties licensed many trades, including peddlers, saloons, theaters, pawnbrokers, and taxis, and building departments issued permits for new storefronts, signs, and conversions. Where these registers survive, they give exact dates, owners' names, and addresses.

Where to Find Business Records

• Incorporation records. Every state's secretary of state (or corporation commission) has a free online business-entity search showing a company's filing date, status, registered agent, and often scanned filings. Records of long-dissolved companies may be missing online; older articles of incorporation are usually at the state archives.
• Assumed-name (DBA) filings. In many states, a person trading under a business name other than their own filed an assumed-name or fictitious-name certificate, often with the county clerk. These name the actual owner of "Main Street Bakery."
• Liquor licenses. Bars, taverns, and restaurants that served alcohol needed licenses from the city, county, or state, and license lists were often printed in the newspaper.
• Building permits. Ask the city or county building department what survives for the address; old permits are often on index cards or microfilm, and some cities have moved them to the municipal archives.

Retention varies widely: some cities kept everything, while others destroyed files after a set number of years. A city archivist or the state archives' local-records staff can tell you what survives.

Tax Records and Assessor Files

Property tax rolls show who owned a commercial building and how its assessed value changed, which helps date construction and expansions. Some places also taxed business inventory or equipment (personal property), and those rolls list the business owner even when the owner rented the building. Older rolls are usually at the county treasurer's office, the courthouse, or the state archives. Ask specifically for personal property tax rolls; staff may not think of them for a business question.

Trade Publications and Business Directories

Every industry had its own directories and journals: lists of breweries, theaters, banks, druggists, and manufacturers, with locations and owners. Many pre-1930 volumes are free to read in full on HathiTrust and Google Books; later volumes are often search-only, which still confirms a business appears before you request the volume from a library.

Credit Reports: R.G. Dun & Co.

For the 19th century, the richest source on small merchants is the credit-report ledgers of R.G. Dun & Co. (a predecessor of Dun & Bradstreet). From the 1840s to the 1890s, local correspondents reported on the reputation, worth, and habits of storekeepers and tradesmen across the country, arranged by state and then by county or city. The handwritten volumes are held at Harvard Business School's Baker Library. They are not online, access requires an application, and staff will search the index for a limited number of names each year, so contact the library before planning a visit.

Telephone Directories

From the mid-20th century, telephone books, especially the Yellow Pages, became the main business listing in many towns as city directories thinned out. The Library of Congress has put part of its telephone directory collection online free, the Internet Archive hosts scanned phone books for many cities, and public libraries often keep local runs. See our guide to searching old phone books online for free.

Oral History and Community Memory

Long-time residents remember what stores sold, who ran them, and why they closed, and many of those details were never written down. Bring a printed map or a directory page to the conversation and ask about a specific block: "What was on the corner of Main and Elm when you were a kid?" Record interviews with permission, note names and approximate years, and check them against directories, which confirm dates far better than memory does. Ask your local historical society whether it already holds oral histories of the neighborhood.

Photographs and Postcards

Street photographs and real-photo postcards caught storefronts, signs, and delivery wagons. Search local historical society and library photo collections by street and by business name, then the large free collections such as the Library of Congress and statewide digital libraries. For businesses that closed in the last twenty years, Google Street View's "See more dates" timeline often shows the old signage. Our guide to finding old photos of a house or street lists more sources, and dating old photographs helps place an undated storefront picture.

Census Records for Business Research

Population censuses through 1950 (free at FamilySearch and the National Archives) record each person's occupation, and from 1910 the industry they worked in, which confirms an owner's trade and family. The federal government also took nonpopulation schedules: manufacturing or industry schedules survive for 1820, 1850, 1860, 1870, and 1880 and list individual establishments, with the owner's name, the product, the capital invested, and the number of employees. Very small shops were left out. No nonpopulation schedules survive after 1880. They are held state by state: some on National Archives microfilm, others at state archives and libraries, and some are indexed on FamilySearch. The National Archives' nonpopulation census page lists where each state's schedules are.

Historical Society Resources

Local historical societies often keep business files of clippings, photographs, ledgers, menus, and letterhead, and sometimes the records of a firm that closed and donated its papers. Email ahead with the business name, address, and years you are researching. Use our directory of historical societies by state to find the organization that covers the address.

Specialized Business Records

Banking and Financial Institutions

The FDIC's free BankFind Suite lists current and former FDIC-insured banks, including ones that closed or merged, with their history of name changes and acquisitions. For earlier banks, look for the annual reports of your state's banking department, which listed each state-chartered bank, its officers, and its condition; many are on HathiTrust and Google Books.

Restaurants and Bars

Liquor license records and health-inspection files can document restaurants and taverns that left few other traces. Menus, matchbooks, and postcards turn up in historical society collections and library menu collections, and newspaper restaurant ads give opening dates and owners.

Manufacturing

For factories, combine the census manufacturing schedules above with state industrial directories, the state labor bureau's annual reports (many listed factories and their employees by town), and Sanborn maps, which drew industrial plants in detail. Companies that lasted long often published anniversary histories, which you can find through WorldCat or your library's catalog.

Overcoming Common Research Challenges

Address Changes

Many cities renumbered streets in the late 1800s and early 1900s. If a business seems to "move" between directory editions without changing anything else, suspect renumbering. Directories from the changeover year sometimes printed conversion tables, and Sanborn maps often show both old and new numbers.

Name Variations

"Smith's Grocery," "Smith Grocery Co.," and "B. Smith, grocer" may all be one store. Track the owner's name and the address alongside the business name, since those changed less often.

Limited Records for Small Businesses

Small shops, home businesses, and businesses serving immigrant or Black communities were often undercounted in directories and ignored by the mainstream press. Look for community-specific newspapers, church and fraternal records, and ethnic or business directories published by the communities themselves, and ask local historical societies about oral histories.

Tips for Business Research

• Build a year-by-year table. One row per year, with the occupant from each source you check; gaps and conflicts become obvious.
• Confirm with two sources. A directory listing backed by a newspaper ad or a Sanborn label is far more reliable than either alone.
• Search the owner, not just the business. Owners' obituaries often give the firm's founding year and history.
• Check the Wayback Machine for recent closures. The Internet Archive's Wayback Machine has saved web pages since 1996, including many small-business websites that no longer exist.
• Record your sources. Note the directory year and page, or the newspaper date and page, for every fact.

Frequently Asked Questions

How do I find records of a business that no longer exists?

Search the business name in your state's secretary of state business-entity database for incorporation and dissolution dates, then in city directories and newspapers for addresses, owners, and years of operation. Assumed-name filings at the county clerk, license records, and local historical society business files fill in the rest.

How can I find out who owned a business in the past?

City directories usually name the proprietor in the alphabetical listing or display ad. Assumed-name certificates name the person behind a trade name, incorporation papers name the incorporators and officers, and newspaper notices and obituaries often give the owner's story.

Are old business records free to search?

Mostly, yes. Scanned city directories on the Internet Archive and FamilySearch, Chronicling America, the Library of Congress Sanborn maps, state business-entity searches, and the FDIC's BankFind Suite are free. Copies of older state or county filings may carry a small fee.

What are the R.G. Dun credit reports?

They are handwritten credit-report ledgers kept by R.G. Dun & Co. from the 1840s to the 1890s, describing the reputation and finances of merchants and tradesmen across the United States. The volumes are at Harvard Business School's Baker Library, are not online, and require an application to use.

Which census records list businesses?

The manufacturing or industry schedules of 1820, 1850, 1860, 1870, and 1880 list individual establishments with owners, products, and employees, though small shops were left out. Regular population schedules through 1950 give each person's occupation.
