The basic characteristic of literary works is that they reflect social life with images. In the process of creating a literary work, the writer always carries out the activity (or way) of figurative thinking. It has three features:

First of all, the writer uses various artistic means to fuse a large number of perceptual materials obtained from life into living artistic images; secondly, it is always inseparable from imagination (fantasy, association) and fiction; Thirdly, it is always accompanied by strong emotional activity.

The process of creating visual thinking of literary works determines that there is a fundamental difference between literary works and the disciplinary works created by scientists using logical thinking, and the difference can be understood from the following five aspects:

1. In terms of content, although they are all reflections of objective things, the subject works adopt a "scientific grasp of the world", the materials are detailed and accurate, the time, place, people, causes, processes, and results of events must be true, the shape, size, nature, characteristics, and uses of things must be accurate, the figures, charts, and examples cited must be reliable, and everything has objective reality; Literary works, on the other hand, adopt a "way of mastering the art of the world", which is based on life and fiction, never sticking to real people and real events, characters do not use a model but take many people together and become one, events do not use facts but take one end and generate them, the environment is not just relying on one place and one place but is combined and created according to needs, everything has objective rationality.

2. In terms of form, although the medium they use is language, the language of the subject works is simple and clear; The language of literary works is more important than the flying style.

3. From the author's point of view, they are all the fruits of thinking, but the subject works mainly use logical thinking, speaking with objective facts, statistics, logical judgments and reasoning; Literary works, on the other hand, mainly use figurative thinking, depicting speech with vivid and touching images.

4. From the reader's point of view, they all have cognitive value, but the subject works appeal to the reader with facts and reason, and the connoisseur focuses on the evaluation of the truth and practical function of science; While literary works appeal to the reader's feelings and imagination, the connoisseur focuses on the judgment of artistic truth and aesthetic creation.

5. In terms of function, they all have social value, but the subject works are mainly tools for transmitting information, focusing on practicality; Literary works are a means of social influence, focusing on aesthetics.

From the comparison of the above characteristics, we can conclude that the difference between a literary work and other works is that it does not aim to convey specific specific knowledge, and it is impossible to obtain scientific and technological expertise or specific scientific experiments, production and working methods through reading literary works. If the main purpose of a work is to convey specific specific knowledge, then it does not belong to the category of literature, even if it has beautiful literary value, such as Sima Qian's "Records of the Historians".

By grasping the essential differences between literary works and other works, we will be able to index them with more confidence in the process of classification and indexing. Of course, there are some special rules for book classification, and they must be indexed according to these rules.
