External characteristic pathways.

Title pathway. It is a way to search for literature according to its title. Generally, it is used to find books, periodicals, and single documents.

Author's Pathway. It is a way to search for documents based on the names of known authors. Through the author's channel, you can retrieve the main literature information of a certain author's research on a certain topic.

Number Route. is a way to find documents by known number. Such as patent number.

indexes, standard number indexes of standard documents, etc.

Other avenues. It is an auxiliary search method, through a special way to find the index of the required literature. Such as drug name index, molecular formula index, etc.

Literature search steps.

Literature retrieval is the process of searching for literature according to the requirements of the subject, using search tools, and following certain steps. The scientific arrangement of the search steps is called the search strategy. The retrieval strategy is an information retrieval scheme designed for retrieval questions, the use of retrieval search and technology, and its purpose is to achieve a certain accuracy and recall rate.

Literature searches generally go through the following steps:

Analyze the topic and develop a search strategy.

First of all, it is necessary to understand the purpose and significance of the topic, clarify the theme, research points and main characteristics of the topic, and then formulate a search strategy according to the characteristics and search requirements of the topic. The formulation of search strategy includes search questions, selection of search methods, selection of search tools, and limitation of search scope (specialty, time, language, document type), etc., among which the most important is to determine the search identifier, such as keywords, subject headings, classification numbers, authors, author affiliations, etc. The search identifier is composed of Boolean logical relationships.

Use search tools to find literature clues.

According to the needs of the subject search, select the relevant search tools, and then use the constituted search questions, search the relevant indexes according to the corresponding search paths, and then find the corresponding literature clues in the literature part or bibliographic part according to the address indicated by the index, such as the title, content abstract, author and author affiliation, document source, etc.

Obtain original documents based on the source of the document.

First of all, the source of the document should be identified by the type of the document, the abbreviation should be restored to the original name, and then the corresponding collection catalog and collection unit should be searched according to the full name of the document source, and then the original text should be borrowed or copied.

What are the general search methods for searching from the content characteristics of literature?

1. Internal features.

Meaning: Systematic Classification Language—Taxonomic Index; Subject language (headings—headings index. Unit Words—Unit Word Index, Keywords—Keyword Index, Thesaurus-Thesaurus Index); **Language (various special indexes such as molecular formulas - Lao Xiang molecular formula indexes, structural formulas - structural formula indexes).

Purpose: The title of the document (i.e., the title of the document), the name of the author, the publisher, the report number, and the patent number.

Search for the contents of the reed calendar.

2. External features.

Meaning: The search language of the external features of the document mainly refers to the title (title), author's name, publisher, report number, patent number, etc. Different documents are arranged according to the alphabetical order of the title and author name, or according to the number of the report number and patent number, and the search language is formed to meet the needs of users by the search method of the title, author and number.

Purpose: Search the title of the document (i.e., the title of the document), the name of the author, the publisher, the report number, the patent number, etc.

According to the classification and arrangement of the subject attributes to which the subject content belongs, the categories are sorted according to the internal logical relationship of the discipline knowledge system, and the subject attributes are used as the classification criteria for family search. It can reflect the conceptual affiliation, hierarchy, derivation, and parallel relationships of disciplines.

The main advantage of the classification method is that it is classified according to the logical law of scientific classification and combined with the characteristics of book categories, from the superior to the lower level, the classification method is concise and easy to remember, the hierarchy is clear, and the similar books and periodicals are concentrated, and the retrieval is easy. However, when it comes to intersecting disciplines or disciplines that are rapidly differentiated, this method is not very specific.

The appearance of the literature is characterized by the search of the title of the document (i.e., the title of the document), the name of the author, the publisher, the report number, the patent number, etc. Different documents are arranged according to the word order of the title and author name, or according to the number of report number and patent number, and the search language is formed to meet the needs of users with rolling debate.

The external features of a document are a kind of literature retrieval language, and the search language that describes the external features of a document can be briefly summarized as:

1. Title - Title index.

2. Author's call for reserve - author index, group author index.

3. Document number - report number index, contract number index, access number index.

4. Others - name index, citation bibliography, etc.

Document Name Pathway.

Author's name.

Authors, editors, translators, etc.

Literature** Approach.

Such as patent number, report number, contract number, standard number, international standard book number and journal number, etc.

Classification approach: The method of searching for literature according to the subject classification system.

Molecular formula pathway: This is a way to search for literature based on the molecular formula of a chemical substance as a search identifier.

Citation route: The references or citations attached to the document are one of the external characteristics of the document. The indexing system that uses this type of citation, known as the citation indexing system, provides a way to retrieve citations from the cited.

Serial number: including report number, standard number, patent number, registration number, etc. This is a way to find literature based on a specific number, etc.

There are several ways to find a document from its content characteristics:

Academic search engines are one of the most commonly used ways to find literature.
