Primary sources are the most valuable sources of information to modern historians and to ancient historians. Primary sources are ironclad proof and can stand alone on their own. They include such things as birth, death, and marriage records; wills; property records; legal documents; charters; firsthand accounts; tombstones; censuses; surveys; letters; personal records; military service records; baptismal records; official court records (as in royal court/king's court); rolls of all kinds; registers. Historians love primary sources because it makes their work much easier and more credible. Secondary sources are not as ironclad as primary sources. Historians use these sources when primary sources aren't available or known. Secondary sources include things like chronicles and narratives written by monks/concurrent historians, hearsay, old pedigrees, church records; tradition, and records or written information that have no solid, underlying proof. No matter how many secondary sources someone might use to bolster a statement, it is not considered to be foolproof evidence. It's similar to the idea of proof in a trial: Eyewitness testimony and documentation are believable; whereas hearsay and opinions aren't.

Historians need access to primary sources such as documents, artifacts, and oral histories to conduct research. They also require critical thinking skills to analyze and interpret historical evidence accurately. Additionally, knowledge of historiography, research methods, and relevant theories are essential tools for historians.
