I would like to ask, what are the characteristics of literature information?

The external feature of literature is a literature retrieval language. The retrieval language of the external characteristics of literature mainly refers to the retrieval of the title, author's name, publishing house, report number, patent number and other contents of literature. A retrieval language that arranges different documents according to the word order of article titles and authors' names or according to the numerical order of report numbers and patent numbers to meet the needs of users.

Literature is the carrier of all recorded knowledge. This definition seems simple, but it is objective, comprehensive and rigorous.

From the literal meaning of the definition, it is not difficult to see that the literature described here basically has three elements. One is the carrier itself, the other is the content contained in the carrier, and the third is the recording method or means of the carrier content.

Obviously, according to the definition of literature, the special carrier of literature must meet three basic conditions at the same time: first, it must have certain information and knowledge content, second, it must use certain recording means, and third, it must show certain carrier forms.

Information and knowledge are the main body of literature. Without information and knowledge, any form of carrier can only be called material, not literature. Any form and type of literature must first have certain information and knowledge content as the premise.
