Some technical explanations about the integrated classification of books:
⒈ The version year, the author indicates that it belongs to the business scope of the publishing house, it has been indicated in the published book, and it is repeated in the classification number It will burden the reader. Advocating simplicity is the professional ethics of librarians. Resolutely retain what is necessary and resolutely eliminate what is unnecessary. Cancel the recommendation number. The request number and book number are replaced by the collection number, and the collection classification number is used to unify the title.
⒉ There is overlap in subject content, and concepts have their essential attributes and non-essential attributes. Generally, they should be classified into one category, and the division should be based on conceptual words that reveal essential attributes. Interdisciplinary subjects generally follow the discipline positioning laws and are also restricted by discipline standards and are special.
⒊ The subject classification of books is different from the subject classification standards; the book subject codes of this classification are special book subject codes suitable for libraries. Book classification numbers can be used universally for book publishing.
⒋ There is no general complex table, general complex table, imitation table, or simplified table, no comprehensive books are divided, no structural control of the total fraction is used, and no original carry conversion system is used.
