In scholarship, a secondary source [1] [2] is a document or recording that relates or discusses information originally presented elsewhere. A secondary source contrasts with a primary, or original, source of the information being discussed. A primary source can be a person with direct knowledge of a situation or it may be a document created by such a person.
A secondary source is one that gives information about a primary source. In a secondary source, the original information is selected, modified and arranged in a suitable format. Secondary sources involve generalization, analysis, interpretation, or evaluation of the original information.
The most accurate classification for any given source is not always obvious. Primary and secondary are relative terms, and some sources may be classified as primary or secondary, depending on how they are used. [3] [4] [5] [6] A third level, the tertiary source, such as an encyclopedia or dictionary, resembles a secondary source in that it contains analysis, but a tertiary source has a different purpose; it aims to elaborate a broad introductory overview of the topic at hand. [1] [7]
Information can be interpreted from a wide variety of found objects, but source classification for primary or secondary status, etc., is applicable only to symbolic sources, which are those objects meant to communicate information, either publicly or privately, to some person, known or unknown. Typical symbolic sources include written documents such as letters, notes, receipts, ledgers, manuscripts, reports, or public signage, or graphic art, etc,; but do not include, for example, bits of broken pottery or scraps of food excavated from a midden —and this regardless of how much information can be extracted from an ancient trash heap, or how little can be extracted from a written document. [8]
Making distinctions between primary and secondary symbolic sources is both subjective and contextual, [9] such that precise definitions can sometimes be difficult to make. [10] And indeed many sources can be classified as either primary or secondary based upon the context in which they are being considered. [8] For example, if in careful study a historical text discusses certain old documents to the point of disclosing a new historical conclusion, then that historical text may now be considered a primary source for the new conclusion, but it is still a secondary source as regarding the old documents. [11] Other examples for which a source can be assigned both primary and secondary roles would include an obituary or a survey of several volumes of a journal to count the frequency of articles on a certain topic. [12]
Further, whether a source is regarded as primary or secondary in a given context may change over time, depending upon the past and present states of knowledge within the field of study. [13] For example, if a certain document refers to the contents of a previous but undiscovered letter, that document may be considered "primary", because it is the closest known thing to an original source—but if the missing letter is later found, that certain document may then be considered "secondary". [14]
Attempts to map or model scientific and scholarly communications need the concepts of primary, secondary and further "levels" of classification. One such model is provided by the United Nations as the UNISIST model of information dissemination. Within such a model, source classification concepts are defined in relation to each other, and acceptance of a particular way of defining the concepts for classification are connected to efficiently using the model. (Note: UNISIST is the United Nations International Scientific Information System; it is a model of a social system for communications between knowledge producers, knowledge users, and their intermediaries. The system also comprises institutions such as libraries, research institutes, and publishers.) [15]
Some modern languages use more than one word for the English word "source". German usually uses Sekundärliteratur ("secondary literature") for secondary sources regarding historical facts, leaving Sekundärquelle ("secondary source") to historiography. A Sekundärquelle may be a source, perhaps a letter, that quotes from a lost Primärquelle ("primary source")—say a report of minutes that is not known to still exist—such that the report of minutes is unavailable to the researcher as the sought-after Primärquelle.
In general, secondary sources in a scientific context may be referred to as "secondary literature", [16] and can be self-described as review articles or meta-analysis.
Primary source materials are typically defined as "original research papers written by the scientists who actually conducted the study." An example of primary source material is the Purpose, Methods, Results, Conclusions sections of a research paper (in IMRAD style) in a scientific journal by the authors who conducted the study. [17] In some fields, a secondary source may include a summary of the literature in the introduction of a scientific paper, a description of what is known about a disease or treatment in a chapter in a reference book, or a synthesis written to review available literature. [17] A survey of previous work in the field in a primary peer-reviewed source is secondary source information. This allows secondary sourcing of recent findings in areas where full review articles have not yet been published.
A book review that contains the judgment of the reviewer about the book is a primary source for the reviewer's opinion, and a secondary source for the contents of the book. [18] [19] A summary of the book within a review is a secondary source.
In library and information sciences, secondary sources are generally regarded as those sources that summarize or add commentary to primary sources in the context of the particular information or idea under study. [1] [2]
An important use of secondary sources in the field of mathematics has been to make difficult mathematical ideas and proofs from primary sources more accessible to the public; [20] in other sciences tertiary sources are expected to fulfill the introductory role.
Secondary sources in history and humanities are usually books or scholarly journals, from the perspective of a later interpreter, especially by a later scholar. In the humanities, a peer reviewed article is always a secondary source. The delineation of sources as primary and secondary first arose in the field of historiography, as historians attempted to identify and classify the sources of historical writing. In scholarly writing, an important objective of classifying sources is to determine the independence and reliability of sources. [21] In original scholarly writing, historians rely on primary sources, read in the context of the scholarly interpretations. [22]
Following the Rankean model established by German scholarship in the 19th century, historians use archives of primary sources. [23] Most undergraduate research projects rely on secondary source material, with perhaps snippets of primary sources. [24]
In the legal field, source classification is important because the persuasiveness of a source usually depends upon its history. Primary sources may include cases, constitutions, statutes, administrative regulations, and other sources of binding legal authority, while secondary legal sources may include books, the headnotes of case reports, articles, and encyclopedias. [25] Legal writers usually prefer to cite primary sources because only primary sources are authoritative and precedential, while secondary sources are only persuasive at best. [26]
"A secondary source is a record or statement of an event or circumstance made by a non-eyewitness or by someone not closely connected with the event or circumstances, recorded or stated verbally either at or sometime after the event, or by an eye-witness at a time after the event when the fallibility of memory is an important factor." [27] Consequently, according to this definition, a first-hand account written long after the event "when the fallibility of memory is an important factor" is a secondary source, even though it may be the first published description of that event.
An autobiography or a memoir can be a secondary source in history or the humanities when used for information about topics other than its subject. [28] For example, many first-hand accounts of events in World War I written in the post-war years were influenced by the then prevailing perception of the war, which was significantly different from contemporary opinion. [29]
Historiography is the study of the methods used by historians in developing history as an academic discipline, and by extension, the term historiography is any body of historical work on a particular subject. The historiography of a specific topic covers how historians have studied that topic by using particular sources, techniques of research, and theoretical approaches to the interpretation of documentary sources. Scholars discuss historiography by topic—such as the historiography of the United Kingdom, of WWII, of the pre-Columbian Americas, of early Islam, and of China—and different approaches to the work and the genres of history, such as political history and social history. Beginning in the nineteenth century, the development of academic history produced a great corpus of historiographic literature. The extent to which historians are influenced by their own groups and loyalties—such as to their nation state—remains a debated question.
A historian is a person who studies and writes about the past and is regarded as an authority on it. Historians are concerned with the continuous, methodical narrative and research of past events as relating to the human race; as well as the study of all history in time. Some historians are recognized by publications or training and experience. "Historian" became a professional occupation in the late nineteenth century as research universities were emerging in Germany and elsewhere.
Research is "creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization, and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion of past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole.
In the study of history as an academic discipline, a primary source is an artifact, document, diary, manuscript, autobiography, recording, or any other source of information that was created at the time under study. It serves as an original source of information about the topic. Similar definitions can be used in library science and other areas of scholarship, although different fields have somewhat different definitions.
The historiography of science or the historiography of the history of science is the study of the history and methodology of the sub-discipline of history, known as the history of science, including its disciplinary aspects and practices and the study of its own historical development.
Historical thinking is a set of critical literacy skills for evaluating and analyzing primary source documents to construct a meaningful account of the past. Sometimes called historical reasoning skills, historical thinking skills are frequently described in contrast to historical content knowledge such as names, dates, and places. This dichotomous presentation is often misinterpreted as a claim for the superiority of one form of knowing over the other. The distinction is generally made to underscore the importance of developing thinking skills that can be applied when individuals encounter any historical content. History educators have varying perspectives about the extent they should emphasize facts about the past, moral lessons, connections to current events, or historical thinking skills and different belief about what historical thinking involves.
The scholarly method or scholarship is the body of principles and practices used by scholars and academics to make their claims about their subjects of expertise as valid and trustworthy as possible, and to make them known to the scholarly public. It comprises the methods that systemically advance the teaching, research, and practice of a scholarly or academic field of study through rigorous inquiry. Scholarship is creative, can be documented, can be replicated or elaborated, and can be and is peer reviewed through various methods. The scholarly method includes the subcategories of the scientific method, with which scientists bolster their claims, and the historical method, with which historians verify their claims.
A tertiary source is an index or textual consolidation of already published primary and secondary sources that does not provide additional interpretations or analysis of the sources. Some tertiary sources can be used as an aid to find key (seminal) sources, key terms, general common knowledge and established mainstream science on a topic. The exact definition of tertiary varies by academic field.
Historical method is the collection of techniques and guidelines that historians use to research and write histories of the past. Secondary sources, primary sources and material evidence such as that derived from archaeology may all be drawn on, and the historian's skill lies in identifying these sources, evaluating their relative authority, and combining their testimony appropriately in order to construct an accurate and reliable picture of past events and environments.
Source criticism is the process of evaluating an information source, i.e.: a document, a person, a speech, a fingerprint, a photo, an observation, or anything used in order to obtain knowledge. In relation to a given purpose, a given information source may be more or less valid, reliable or relevant. Broadly, "source criticism" is the interdisciplinary study of how information sources are evaluated for given tasks.
The following outline is provided as an overview of and topical guide to history:
A source text is a text from which information or ideas are derived. In translation, a source text is the original text that is to be translated into another language.
Recorded history or written history describes the historical events that have been recorded in a written form or other documented communication which are subsequently evaluated by historians using the historical method. For broader world history, recorded history begins with the accounts of the ancient world around the 4th millennium BCE, and it coincides with the invention of writing.
A biography, or simply bio, is a detailed description of a person's life. It involves more than just basic facts like education, work, relationships, and death; it portrays a person's experience of these life events. Unlike a profile or curriculum vitae (résumé), a biography presents a subject's life story, highlighting various aspects of their life, including intimate details of experience, and may include an analysis of the subject's personality.
Pauline Alice Maier was a revisionist historian of the American Revolution, whose work also addressed the late colonial period and the history of the United States after the end of the Revolutionary War. She was the William R. Kenan, Jr. Professor of American History at the Massachusetts Institute of Technology (MIT).
History is the systematic study and documentation of the human past. History is an academic discipline which uses a narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians debate which narrative best explains an event, as well as the significance of different causes and effects. Historians debate the nature of history as an end in itself, and its usefulness in giving perspective on the problems of the present.
The UNISIST model of information dissemination was proposed in 1971 by the United Nations. UNISIST is a model of the social system of communication, which consists of knowledge producers, intermediaries, and users. These groups of people are different kinds of professionals. The social system also contains institutes such as research institutes, publishers, and libraries. The actors and institutions perform information services such as writing, publishing, storing and retrieving documents and information. The actors are communicating in both formal and informal ways and they are producing different kinds of documents such as journal articles, books, book reviews, proceedings, bibliographies and catalogues, dictionaries, handbooks, encyclopedias and review articles.
Source literature is a kind of information source. It might, for example, be cited and used as sources in academic writings, and then called the literature on the subject.
This glossary of history is a list of definitions of terms and concepts relevant to the study of history and its related fields and sub-disciplines, including both prehistory and the period of human history.
A historical source encompasses "every kind of evidence that human beings have left of their past activities — the written word and spoken word, the shape of the landscape and the material artefact, the fine arts as well as photography and film."
[T]he distinction is not a sharp one. Since a source is only a source in a specific historical context, the same source object can be both a primary or secondary source according to what it is used for.
[T]he same document can be a primary or a secondary source depending on the particular analysis the historian is doing,
[A] source may be primary or secondary, depending on what the researcher is looking for.
[T]he term 'primary' inevitably carries a relative meaning insofar as it defines those pieces of information that stand in closest relationship to an event or process in the present state of our knowledge. Indeed, in most instances, the very nature of a primary source tells us that it is actually derivative.…[H]istorians have no choice but to regard certain of the available sources as 'primary' since they are as near to truly original sources as they can now secure.
The purpose of a secondary source is to make the primary sources accessible to you. If you can read and understand the primary sources without reading this book, more power to you. If you read this book without reading the primary sources you are like a man who carries a sack lunch to a banquet
