Lockport Directory Years on Shelf
White Oak Library's Lockport holdings provide the clearest edition inventory. The list is not an unbroken annual run. Early town directories sit beside telephone books, combined-community volumes, Lockport editions, Joliet directories, and Polk regional books. A missed year may reflect a shelf gap, a title change, or a wider edition that filed Lockport under a regional heading.
| Collection | Years represented | Where held | Access |
|---|---|---|---|
| Lockport city directories | 1859/60, 1872/73, 1899/1900 | White Oak Library | Ask at branch |
| Lockport telephone books | 1924-1939, 1940-1941, 1944-1952 | White Oak Library | In library |
| Lemont, Lockport, Plainfield | 1927/28 | White Oak Library | Combined edition |
| Lockport Illinois directories | 1963, 1968, 1973-1980, 1982-1987, 1989-1990, 1992-1993 | White Oak Library | In library |
| Joliet and Polk area | Selected 1981-1999; Polk 2000-2007, 2009-2020 | White Oak Library | Confirm coverage |
The inventory does not promise that each book has a reverse street section. Ask whether an edition includes householder, business, telephone, or street-order pages. The shelf reaches 2020, yet it is historical evidence rather than a live roll of all Lockport residents.
Lockport City Directory Research Desk
The White Oak Lockport Branch is at 121 E. 8th Street, phone 815-552-4250. Listed hours are Monday through Thursday, 9:00 a.m. to 9:00 p.m.; Friday and Saturday, 9:00 a.m. to 5:00 p.m.; and Sunday closed. Confirm hours before traveling.
Bring a surname, spelling variants, and a ten-year range. Staff can connect a request to city directories, telephone books, Lockport Township High School yearbooks, LAGHS newsletters, or the Will County Historical Society Quarterly. Local-history reference items remain in the library. Record the title, year, page, and call number while the volume is open.
The White Oak local-history overview shows the research collection.

The captured page leads to the local collection, where staff can confirm editions and companion files.
Read a Lockport Directory Entry
No person-level Lockport entry was available in a free official viewer during research, so a fictional sample would mislead. Read the actual edition key first. Depending on publisher and year, an entry may show a name, initials, occupation, business, spouse or household clue, street address, or telephone listing. Absence is not proof that someone left Lockport.
| Printed name | May use initials, a formal name, or changing spelling. |
|---|---|
| Work or trade | May identify an occupation or employer. |
| Street line | Could be a home, business, subscriber, or institution. |
| Household clue | Some editions identify a spouse or household head. |
| Edition key | Defines that publisher's marks and shortened words. |
Compare the same person across two editions. A move, omission, changed initials, or regional title may explain why a line changes.
- Criss-cross directory
- A section arranged by street or phone, not surname. White Oak has not confirmed which Lockport books contain one.
- Householder index
- A street-order listing that may name a household contact.
- Abbreviation key
- The edition's guide to shortened occupations, streets, and symbols.
Lockport Names Beyond Directories
The Local History Vertical Files Index groups material under Illinois, the Illinois and Michigan Canal, Library, Lockport, People, and Will County. Files may hold clippings and reports that never appeared in a city directory. Archive boxes can contain photographs, ledgers, and fragile original papers.
Yearbooks from 1926 to the present help distinguish classmates with similar names. Some digital copies are available through Biblioboard; physical sources require an in-house request. Ask for a folder, box, yearbook page, or newsletter issue. A precise citation lets another researcher return to the same source.
Map Lockport Directory Addresses
City directories name people; Sanborn maps describe blocks and structures. The University of Illinois Sanborn inventory lists Lockport maps for 1886, 1891, 1897, 1902, 1909, and 1926. The 1886 set has four colored sheets at 50 feet per inch. Sheet one contains its key and index.
Maps can show factory or commercial occupancy, house and block numbers, construction, openings, and water details. They do not list every resident. Find the period block from the directory address and record the sheet number. Never assume an old block equals a current parcel.
The official Lockport Sanborn holdings list appears below.

The year list pairs a street found in a Lockport city directory with the nearest available map edition.
Lockport Directory Access Through Time
Repository history explains changing labels on citations. A volume now at White Oak may bear an older library name. Preserve the name printed in the source, then identify its current keeper.
| Year | Milestone |
|---|---|
| 1859/60 | Earliest Lockport directory listed by White Oak |
| 1922 | Woman's Club began a public-library effort |
| 1929 | Township library established |
| 1932 | Boyer residence became a library |
| 1965/66 | New building opened |
| 1981 | Library joined a district |
| 2013 | Renovated Lockport Branch reopened |
Telephone and Polk city directories add a long twentieth-century layer, but their coverage is selective. They may feature a subscriber or household head while leaving others out.
Runyonstown in Lockport Directory Searches
Older research needs older words. The City of Lockport history traces Armstead Runyon's 1830 settlement by Fiddyment Creek, the Runyonstown name, and William Gooding's canal and water-power work. Search those terms with a surname in maps, vertical files, and newspapers.
The Illinois and Michigan Canal is a record key, not just a landmark. Canal, mill, rail, industrial, village, and township words can uncover a person whose address does not match a modern label. The city directory gives one dated clue; a map or paper can explain it.
Note: Attach each historic term to a dated edition, map sheet, article, or official summary before treating it as evidence.
Trace Lockport Families by Directory
Follow a household in documented steps. Pair directory years with census years only when names, places, and dates support the link. A city directory can be stale or selective, and a missing line has several possible causes.
- Write the full name, initials, spelling variants, and a ten-year range.
- Search the Lockport edition before a Joliet or Polk regional volume.
- Record title, publisher, year, page, and listing type.
- Compare the street with the nearest census year and Sanborn sheet.
- Use a yearbook, newspaper, cemetery record, or deed as a separate check.
A person who vanishes may have moved, died, changed how the name was printed, or gone unlisted. For a modern check, use the Lockport resident lookup and keep current records separate from the historic shelf.
When the Lockport shelf lacks a needed year, use the Illinois State Archives repository inventory as a finding aid. It lists regional directories, census material, cemetery sources, newspapers, an atlas, and Sanborn maps. Confirm the exact title, year, format, and current keeper before traveling because an inventory does not guarantee that every item remains available.
An older Illinois State Geological Survey inventory also describes Will County microfiche, Lockport volumes, L.S. Thomas editions, and Polk runs. A book may have moved or been reclassified. FamilySearch's directory collection provides another route for names, occupations, and addresses, though access can depend on login, rights, and the exact volume. None of these alternatives replaces a full edition-level citation.
