Identify the kind of list you have
Censuses, postal directories, business directories and electoral rolls can all contain names and addresses, but they are different sources. A census is created around a particular survey and its questions; a directory gathers householders or businesses for publication; an electoral roll records people eligible and registered to vote. Begin with the title page, preface, arrangement notes and field headings. Establish whether the unit is a person, household, business premises or registration. A page of names does not necessarily list every local resident.
All people and addresses in this article's examples are fictional. Suppose you are looking for the address of Xu Ming and his wife He Fang. A directory lists only Xu Ming, while an electoral roll also includes He Fang. This does not establish that she previously lived elsewhere: the inclusion rules may differ. Explain why each source was created before comparing addresses and dates. For an unfamiliar country or period, consult its archival holdings guide rather than applying census practices from another region.
Check available years and access methods
Do not assume every country retained equivalent household-level census records. Establish whether personal returns exist for the target place and year, whether only statistical summaries survive, whether material is digitised and whether access is restricted. The National Library of Australia identifies historical electoral rolls as useful for tracing addresses and as substitutes for census material in some research. Substitution does not make the fields equivalent: a roll cannot automatically identify children, all household members or other answers asked by a census.
The Library's directory guidance describes arrangements by surname, town, street and occupation. Search the catalogue for the required state or city and check individual volumes, rather than assuming an entire collection includes images for every year. Record missing years and the version actually consulted, distinguishing paper, microform and digital copies. If a year requires a reading-room visit, gather the call number and target street first so the visit addresses a defined question.
Search by name and by street
Name searching is convenient, but address research often requires reading in the reverse direction. Find the name, then check the same street number in the street section for a business name, another householder or nearby landmark. If the name index gives no result, browsing a known street may work better. Transcribe the full street spelling, former name, abbreviation and number, retaining the original alongside any modern equivalent. The same number in another town, or a later street renaming, can send an apparently precise search in the wrong direction.
In the fictional example, Xu Ming appears under initials in the alphabetical section, while the street section supplies a full shop name. The researcher uses the name in a family letter to find the street entry and then returns to the name section. These are two search routes, not two independent sources, because they come from the same book. Check the image rather than relying on recognised text. Save the title page, entry and street page so others can understand the edition, arrangement and address coverage.
Successive years are more useful than one address
Build a year-by-year table showing edition year, entry name, address, occupation, reference and whether no entry was found or the source was not consulted. Searching an available year unsuccessfully is different from having no source for that year. Examine the years around a discovered entry to trace when a name or business appears, disappears or moves to another street. Do not automatically equate publication year with address-collection year. Record any editorial cutoff specified in the preface.
If someone appears one year and disappears the next, the initial conclusion is only that the entry was not found in that edition. Moving, death, omission, a name change, altered arrangement or repeated information from an earlier year require other sources to assess. The fictional Xu Ming changes streets between editions, but this could represent a household move or only a business relocation. Put residence and business premises on separate timeline lines and compare envelopes, registrations or other records before describing it as the whole family moving.
Housemates and neighbours provide leads
Several adults at one address do not automatically form a family. They may be lodgers, tenants, employees or separate households; if the source gives no kinship information, do not add it. Where a census does supply relationships, establish which recorded person they are relative to. Mark housemates and neighbours as leads, then seek certificates, letters or other material directly describing relationships. This prevents an entire street being connected into a family tree.
Neighbours can help distinguish people with the same name, especially when address, occupation and neighbouring businesses recur together. In the fictional example, two men named Xu Ming live in different districts, but only one is beside the bakery mentioned in a family letter. This increases the candidate's relevance without confirming identity. List supporting details and possible counterexamples, then seek age, spouse or explicit address evidence. Proximity establishes geography, not personal association.
Recognise omissions and boundaries
Electoral rolls list people eligible and enrolled under contemporary rules, not the entire population. The absence of children, ineligible people or others not enrolled cannot establish that they left a place. Postal and business directories also have selection rules; women, tenants and people without businesses may not have individual entries. Read the official guidance and edition notes to determine whether a category of person should be expected. Do not project present-day registration rules onto earlier material or interpret silence as an absence of life.
An occupation is also wording in a particular record. It may be general, outdated or refer only to the householder. Retain the original term when transcribing and separately record your interpretation and questions, rather than expanding a short label into a detailed employment history. If a source uses categories or language inappropriate today, explain the recording context and quote only necessary portions. The aim is to understand how a person appeared in institutions and publications while continuing to seek their own account of life.
Write a residential timeline with room for uncertainty
Write that a particular edition records someone at an address, rather than asserting that they lived there continuously from that year to the next. If successive editions support a stable address, state that it recurs in the consulted editions while retaining the gaps between them. Cite the full title, edition, publisher or holding institution, page, district or street, link and access date. For manual browsing, also record the pages actually examined and any unreadable portions to support later checking.
Return the results to the family-history question: was the address near work, which letter can verify the street number, and are there sources about He Fang in her own right? Maps supply spatial context but cannot replace address evidence. The fictional family's story may establish only one residence in several years, yet open the next search for friends, journeys to work and neighbourhood routines. Before they were ancestors, they were people living somewhere. A short line in a directory is a beginning.
