Start with a question and a type of record
A primary source is material created during the period you are studying or by someone directly involved in the event or activity you are investigating. Letters, meeting minutes, photographs, newspapers and government forms can all serve as primary sources. Whether a record is useful depends on your question: a newspaper advertisement might be direct evidence of how a product was marketed, but weak evidence of whether buyers liked it.
Before opening an archive, write down what you want to learn and which records might contain an answer. If you are studying how a neighborhood changed, you might look for maps, planning records, photographs and residents’ correspondence. Name a place, an approximate period and any people or organizations involved. These details give you starting search terms without locking you into a single interpretation.
Choose archives that fit the question
Digital archives differ in what they collect and how they describe it. A local library may hold neighborhood photographs, while a university collection may preserve the papers of an organization. Museum collections can be useful for objects and images; government repositories may provide administrative records. Look for an archive’s collection descriptions or subject guides to see whether its holdings match the people, places and record types in your question.
Check what “digital” means on each site. Some catalogs describe physical items that cannot be viewed online. Others offer scans of selected items rather than an entire collection. A search with few results does not necessarily mean the records never existed. It may mean they have not been digitized, have not been described in detail or are held elsewhere.
Search beyond your first keywords
Begin with two or three specific terms, then vary them. Try an older place name, a person’s full name and surname, an organization’s formal name and abbreviation, or a broader term for the kind of record you need. Historical language may differ from the words you use today. When you find a promising item, note the terms used in its description and try them in a new search.
Use date, format and collection filters when they help, but remove them if the results seem unexpectedly narrow. Many archives organize records by creator or collection rather than by topic. Finding one relevant letter may lead you to a folder, series or collection containing related material. Browsing those neighboring records can reveal sources that a keyword search misses, especially when handwriting has not been transcribed or a scan has only a brief description.
Read the record and its description together
When you open an item, inspect the image or transcription alongside its catalog entry. The description may identify a creator, recipient, date, place and collection, as well as the archive’s identifier for the item. Distinguish information visible in the record from information supplied by a cataloger. If a date is estimated or a person is unidentified, preserve that uncertainty in your notes rather than treating the description as a settled fact.
Consider why the record was made and what it can reasonably show. A letter may tell you what its writer wanted a recipient to believe; a photograph shows a selected view, not everything outside the frame. Compare items from different creators where possible. Also look for missing pages, illegible text, cropped images or gaps in a series. A digital copy makes a source easier to access, but it does not remove the source’s original limitations.
Keep a trail you can follow later
Save enough information to find each item again: its title or description, creator, date as given, collection, holding archive, item identifier and a stable link if one is provided. Record the specific page or image you used. Note whether you consulted a scan, transcription or catalog description, since each may present different information. Check any stated conditions for using or reproducing images before including them in a presentation or publication.
Finally, keep a short search log. List the archives you tried, the terms and filters that worked, and important searches that yielded nothing. This helps you avoid repeating steps and makes it easier to explain the scope of your search. Your goal is not to collect as many files as possible; it is to find records whose origins and limits you understand well enough to use them in answering your question.
