Historical information comes from many sources. Some are obvious. Others require digging. The best investigators learn to use a wide range of sources and to cross-reference information across multiple records. This section introduces the most common and valuable sources for paranormal research.
Libraries. Public and university libraries are among the most valuable resources for historical research. Most libraries have local history sections that contain books, maps, photographs, and documents specific to the area. Reference librarians are trained researchers who can help you find sources you did not know existed. Many libraries also provide access to online databases, newspaper archives, and genealogy resources that would otherwise require paid subscriptions.
Newspapers. Historical newspapers are a treasure trove of information. They contain records of deaths, births, marriages, accidents, crimes, community events, court proceedings, and everyday life. A single newspaper article can confirm or challenge a story that has been told for decades. Online archives like Newspapers.com, Chronicling America (from the Library of Congress), and local library digital collections make searching historical newspapers easier than ever. Search for the location's address, the names of past residents, and any notable events associated with the property.
Historical societies. Local historical societies are dedicated to preserving the history of a specific area. They maintain collections of documents, photographs, maps, and artifacts that are not available anywhere else. Historical society staff and volunteers are often deeply knowledgeable about local stories and can point you to sources you would never find on your own. Many historical societies also publish journals and books that contain detailed local history. Membership in your local historical society is one of the best investments a paranormal investigator can make.
Archives. Government archives, university archives, and specialized collections hold primary source documents that may be essential to your research. Property records, court records, probate files, and other legal documents can reveal who owned a property, when it was built, and what legal issues arose. Some archives require appointments or have access restrictions, but the information they contain is often irreplaceable.
Museums. Local museums often have exhibits and collections related to the area's history. Museum curators can be excellent sources of information and can often direct you to additional resources. Even a small local museum may hold photographs, documents, and artifacts that are relevant to your research.
Government records. County recorder and clerk offices maintain property deeds, marriage licenses, death certificates, and other official documents. Many of these records are now available online, but older records may only be accessible in person or on microfilm. Property deeds can reveal the chain of ownership. Death certificates provide cause of death, which can be relevant to paranormal claims. Census records show who lived at a location, their ages, occupations, and family relationships.
Online address and death-history tools. Online tools can help beginners find leads quickly, but they should be treated as starting points rather than final proof. DiedInHouse.com and similar address-history services may help identify reported deaths, incidents, ownership clues, or public-record leads connected to an address. Genealogy and cemetery tools such as FindAGrave.com and BillionGraves.com can help connect names, dates, burial locations, family relationships, military markers, and cemetery records to a case. These services are useful because they can point you toward names and dates that deserve deeper research, but they can contain gaps or errors. Always verify important findings through county records, death certificates, obituaries, cemetery offices, newspapers, deeds, historical societies, archives, or other independent sources before using them in a case report.
Photographs. Historical photographs can reveal how a location looked at different points in time. They can show changes to the building, the surrounding landscape, and the people who lived there. Libraries, historical societies, and online archives like the Library of Congress and local digital collections are good sources of historical photographs. A photograph from 1900 showing a building that looked very different from today can prompt important questions about what changed and when.
Diaries and letters. Personal writings offer a window into the lives of people who lived at a location. Diaries and letters can reveal events, emotions, and experiences that never made it into official records. These sources are rare and often difficult to access, but when they are available, they can provide invaluable context. Local historical societies and archives may hold collections of personal papers.
This introduction is intentionally kept at a beginner level. The Research Methods track in the curriculum provides detailed instruction on how to access, interpret, and cite each of these source types. For now, the goal is to understand what is available and to develop the habit of seeking out historical context for every location you investigate.
