Other classification methods:
1 year. Edition, the author's mark belongs to the business scope of the publishing house and has been marked in the published books. Repeated labeling in classification numbers will bring a burden to readers. Advocating simplicity is the professional ethics of librarians, which must be resolutely retained, but must be resolutely eliminated. Cancel the recommendation number and request number, replace the book number with the collection number, and unify the book title with the collection classification number.
2. The contents of disciplines are cross-cutting, and concepts have their essential and non-essential attributes. Generally speaking, it should only be classified into one category and divided according to the concept words that reveal the essential attributes. Interdisciplinary subjects generally follow the discipline orientation law and are also restricted by discipline standards, which is special.
3. The subject classification of books is different from the national subject classification standard; The book discipline code of this classification is a special book discipline code suitable for libraries. The book classification number can be used as the general number of book publishing.
4. Do not set up general compound tables, general compound tables, imitation tables and short tables, do not divide comprehensive books, do not use the total score structure, and do not use the original carry conversion system for labeling.
5. Marxism, Sun Wen Doctrine, Mao Zedong Thought and Deng Xiaoping Theory, as political theory disciplines, can be applied to Chinese mainland, Taiwan, Hong Kong and Macao. The types and varieties of books related to them are classified into corresponding disciplines and levels according to this classification.
6. To solve the confusion in the book classification system, we must adjust and straighten out the concepts and categories of disciplines at all levels, classify derived disciplines into traditional disciplines, and list new disciplines appropriately. Cancel the classification of "cultural, scientific, engineering and comprehensive books", re-establish the basic disciplines and subsidiary disciplines of books, and decompose them into corresponding disciplines.
