What are primary, secondary and tertiary literature, and briefly describe the relationship between t

All original documents written on the basis of the author's own experience, research or research results, after public publication or exchange, are called primary documents. Primary literature is the main body of literature, the most basic source of information, and the object of literature retrieval. It is characterized by a relatively specific, detailed, and systematic exposition, with opinions, facts, and conclusions.

Generally, it includes periodicals**, monographs, research reports, conference papers, degrees**, patent specifications, technical standards, technical archives, scientific and technological reports, etc.

Secondary literature is formed through the processing, refining and condensation of primary literature. It transforms large amounts of disparate, disorganized information into an orderly, easy-to-manage system. A document is compressed into entries, also known as records (entry, reference, citation, record), and organized in a certain sequence to become a tool that can be used to find a document.

Secondary literature, also known as secondary information, includes retrieval tools such as catalogs, bibliographies, abstracts, and indexes, which can report and guide clues to primary literature.

The tertiary literature is formed by the collection, synthesis, analysis, and detailed description of the primary and secondary literature. It includes manuals, encyclopedias.

The processing of primary literature, secondary literature and tertiary literature reflects the process of centralization and orderliness of literature, while the user's request for original literature is often a reverse process.

Primary literature, also known as original literature, refers to the literature written by people according to their own scientific experiments and production practices, generally referring to periodicals**, scientific and technological reports**, conferences**, degrees**, patents, etc. Secondary literature, also known as retrieval tools, refers to various retrieval tools formed after processing and sorting of primary information, such as catalogs, bibliographies, abstracts, etc., which do not provide comments on primary information, but only provide retrieval clues of primary literature. Tertiary literature refers to the literature written by synthesizing, analyzing, researching and reviewing the contents of a large number of primary literature.

There are two types: review research and reference tools. The relationship between primary literature, secondary literature and tertiary literature: from primary literature to secondary literature and tertiary literature is a process from broad to contracted, from decentralized to centralized, from unorganized to systematic, and it is also the process of the hierarchical structure of scientific and technological literature resources from disorder to order, from one ordered structure to another perfect ordered structure.

The above is the standard answer.

Periodicals**, patent documents, scientific and technological reports, conference proceedings, and degrees** belong to primary literature.

Table of contents, indexes, and abstracts are secondary literature.

According to the content, nature and processing of the literature, the literature can be divided into: primary literature, secondary literature, and tertiary literature. Primary literature refers to the original literature created on the basis of the author's own research results, such as journals**, research reports, patent specifications, conferences**, etc.

Secondary literature is a type of retrieval tool produced by processing and sorting primary literature, such as bibliography, bibliography, introduction, abstract and so on. Three times the literature is in.

On the basis of the primary and secondary literature, the literature compiled after comprehensive analysis is often referred to as the result of "information research", such as reviews, thematic reviews, annual summaries of disciplines, progress reports, data manuals, etc. Similarly, there are cases where information is divided into primary, secondary, and tertiary information.

Primary literature. (primary document): refers to a document created or written by the author based on his or her own research results, regardless of whether the work of others is referred to or cited at the time of creation, and regardless of the material form in which the document appears, it is a primary document.

Most of the articles published in journals and the first published at scientific and technical conferences are primary publications.

Secondary literature. (secondary document): refers to the product obtained by the document worker after processing, refining and compressing the primary document, and is the instrumental document published and accumulated in order to facilitate the management and use of the primary document.

Search reference books and online search engines are typical secondary literature.

Tertiary literature. (tertiary document): refers to the product of extensive and in-depth analysis and research of relevant primary and secondary literature. Such as encyclopedias, dictionaries, etc.

There are also researchers who add zero literature on the basis of the above classification, which refers to the original literature that has not undergone any processing, such as experimental records, manuscripts, original audio recordings, original video recordings, conversation records, etc. Zero-secondary literature plays an important role in the preservation of original documents, the verification of original data, and the verification of original ideas (right holders).

Primary literature, i.e., original literature, is based on the author's own work experience, observations, or actual scientific research results.

Literature with certain inventions or some new insights created on the basis of it. Generally includes, journal theory.

Papers, monographs, scientific and technological reports, patent descriptions, conferences**, degrees**, technical standards. Wait.

Secondary literature is a large number of primary literature of a certain scope, time or type according to its characteristics to collect, organize, compress, process, and organize and arrange in a certain order.

The search was compiled using these documents.

of the literature. Such as bibliography, index, abstract, bibliography, introduction, etc.

The tertiary literature is to systematically sort out and summarize the primary literature on the basis of making full use of the secondary literature.

and a summary literature compiled from the analysis and synthesis of the core. Such as the review study:

Yearbooks, manuals, encyclopedias. Dictionary. Daquan, etc.; Literature Guides: Specialist Literature Guides, Indexes.

and abstracts, service catalogs, reference book catalogs. Wait.

Zero-secondary literature, refers to:

The most primitive that has not been published in a formal manner or has not entered into social communication.

Literature. Such as: private pen.

Notes, design sketches, experiment notes, draft articles, speeches, meeting minutes, letters, and all kinds.

Internal files, etc.

1. The degree of information processing is different.

Primary literature is a document produced by people directly on the basis of their own practical experience in production, scientific research, social activities, etc., and is often called original literature (or first-class literature), which records hand-buried knowledge and information that is relatively novel, specific and detailed.

Secondary literature is a type of literature produced after processing and sorting of primary literature.

Three times the literature is in.

On the basis of the primary and secondary literature, the literature compiled after comprehensive analysis is often referred to as the result of "intelligence research".

2. The information carrier is different.

Primary literature is usually such as journals**, research reports, patent specifications, conferences**, degrees**, technical standards, etc., which have obvious characteristics such as innovation, practicality and academicity.

Secondary literature, such as bibliography, bibliography, introduction, abstract and other retrieval tools.

Three literatures, such as reviews, thematic reviews, annual summaries of disciplines, progress reports, data manuals, etc.
