Significance of a chemical literature search 15

1. In the vast ocean of knowledge, successful explorers must not only be able to drive the split-early high-speed boat to the predetermined target, but also be able to row a small boat to search calmly; It is necessary not only to master the latest retrieval methods of Internet and electronic resources, but also to learn to use traditional methods to obtain resources from paper books and periodicals.

2. It can expand the field of vision. Marx once likened the use of literature to standing on the shoulders of giants. Possession of literature can broaden the researcher's thinking, deepen the understanding of the problem, and inspire deeper thinking.

Frequent reference to the literature can stand at the forefront of the research field, track the latest research results and methods at home and abroad, and get inspiration from them, find possible answers to solve problems, and make the research topics stand at a higher starting point.

3. Unnecessary repetition can be avoided. One of the basic purposes of literature retrieval is to avoid duplication of work, to avoid repeating problems that others have solved, to avoid repeating mistakes that others have made, to avoid detours, and to improve research efficiency.

The role of literature retrieval in the whole research is even important, and the value of research results is related to the quantity and quality of the literature in possession. Conducting research in the face of a lack of literature and information is often either blind or repetitive at a lower level, which is a waste of people and resources.

Significance of Literature SearchLiterature retrieval refers to the process of searching in libraries, databases, networks and other resources through the literature retrieval tool, so as to obtain documents related to the required information. It is an important part of scientific research and academic writing, and it is also the basis of academic communication in the information age. The purpose of literature search is to obtain the most up-to-date, comprehensive and reliable literature to support research and academic writing.

There are many meanings of literature retrieval, such as literature retrieval is an integral part of scientific research, which helps to grasp the progress of the research on this topic, open up ideas, avoid duplication of work, and raise the research level to a new height, and literature retrieval is also the forerunner of scientific decision-making. Literature search. There are many significances, such as literature retrieval is an integral part of scientific research, which helps to grasp the progress of the research on this topic, open up ideas, avoid duplication of work, and raise the research level to a new height, and literature retrieval is also the precursor of scientific decision-making.

Literature retrieval can be based on the process of obtaining literature according to the needs of study and work. In modern times, literature refers to articles and books with historical value or important library materials related to a certain discipline, and with the development of modern network technology, literature retrieval is more done through computer technology. Literature distribution rules:

Patents, standards, archives are managed by the specialized departments of a country, which are the National Patent Office, the State Bureau of Technical Supervision and the State Archives Office, as well as the corresponding local authorities. Academic** is jointly collected by the National Library of China, the Institute of Scientific and Technological Information of China and the degree-awarding institution. Books, periodicals, conference proceedings and reports are mainly provided by the National Documentation Information System.

The National Documentation Information System includes four systems: the Science and Technology Information System, the Library System of the Academy of Social Sciences, the University Library System and the Public Library System.

In today's era of rapid change and rapid development of science and technology, literature retrieval has become an important tool that must be mastered in order to start a business. Literature retrieval is the basis for further learning: in the development of human civilization for thousands of years, a large number of literature and information materials have been accumulated, and it has become a huge treasure trove of knowledge for human society.

How to make full use of this knowledge to better develop oneself and benefit the society has become a topic that everyone is concerned about. Literature search is the best choice. Through the use of literature search, students can better understand the research status of a certain topic, the difficulties encountered, and the solutions to a certain topic.

In this way, students can avoid wasting human, material and financial resources, and greatly improve the work of students on the problems that have been solved by predecessors. Efficiency. At the same time, it opens up ideas and avoids duplication of effort, so as to raise the level of research to a new level.

On the other hand, through the retrieval of a large number of relevant literatures, students can deeply understand a certain topic and become familiar with its related content, so that students can better grasp the memory and flexibly use the content they have learned.

(1) Avoid repeated research or detours.

2) Save learners' time.

3) is a shortcut to new knowledge.

Information retrieval is the first step in doing scientific research, and it plays a vital role in the process of doing scientific research and writing about scientific research. For chemists, the mastery of a large amount of chemical information must be completed through systematic chemical information retrieval. Traditional manual search methods are time-consuming, laborious and incomplete, and have been gradually replaced by the rapid development of online search.

Retrieving various chemical resources through the Internet has become an important means for chemists to obtain chemical information. The chemical resources on the network are very abundant, and the use of the network to retrieve information is fast, comprehensive and informative, and the workload of ordinary people can be completed within one or two hours for half a year.

The significance of pharmaceutical literature retrieval is that it is easy to store and find.

1. Meaning of Pharmaceutical Literature:

The development of pharmaceutical discipline has continuity, inheritance and accumulation like other disciplines, the development of human society for thousands of years, has accumulated extremely rich and valuable pharmaceutical experience and knowledge, people use words, graphics, symbols to talk about the source of the conversation, audio frequency, ** and other means to record it on a variety of carriers, this record of all carriers of pharmaceutical knowledge is called pharmaceutical literature.

2. The significance of pharmaceutical literature retrieval and merger:

Literature retrieval in a broad sense refers to the process of organizing and storing documents in a certain way, and finding out the relevant leakage and fracture documents according to the needs of users. According to the definition of literature search, the basic significance of pharmaceutical literature search is as follows:

1. Storage. That is, a large number of chaotic and disordered documents are scientifically organized to make them an orderly collection.

2. Search. That is, the use of various search tools that have been organized to retrieve the documents required by users.

Literature search methods and approaches

1. Literature search methods:

1. Commonly used method: Shuncha method: from far to near, until now; Reverse search method: from near to far, mostly start searching in the latest bibliography.

2. Segmentation method: delineate a period of time for screening and identification.

2. Literature search methods:

1. External feature approach: the name of the document must be known, and the use value is not large; Authorship by author: If the author is known, it can be searched by this route. For example, the patent number index can be used to search the patent, and the standard number index can be used to check the standard.

2. Internal characteristic approach: The classification approach takes the category to which the content of the literature belongs in the scientific classification system as the way to find the literature; This is the main search method in foreign countries; Keywords are not standardized and standardized main words, but words with substantive meaning and more important words in the literature, which is one of the commonly used ways at present.
