When readers borrow books, they will find a label on the spine. There are two groups of numbers on the label, the upper group is the classification number and the lower group is the book number. These two sets of numbers constitute the call number. Call number is the basis for determining book shelving.

The call number consists of two groups of numbers: the classification number and the book number. The classification number represents the nature of the subject to which the document content belongs, and it can arrange similar books together. The book number represents the distinguishing number of similar documents and determines the arrangement order of similar books.

ISBN is divided into two types:

Category number: the serial number of books with the same category number, consisting of 1-3 Arabic numerals.

Author's number: It consists of the pinyin initials of the first responsible person (limited to 1) and 3 Arabic numerals.

Different libraries adopt species number or author number according to the collection structure, such as books:

Classification of calling numbers:

Books are arranged in the order of request number (that is, classification number plus author number). They are sorted alphabetically by classification number, the same letter is sorted by the first number after the letter, the same letter and the first number are sorted by the second number, and so on.

1.I247.5 and I25 should be pronounced as I247.5 and I25, so I 247.5 should be in front of I 25 in the shelf.

2. Books with the same classification number are arranged alphabetically according to author number and numerical size, such as H3 19.4/G287, H3 19.4/G37, H3 19.4/H 14, H31.

3. Taking Class I as an example, list the basic order: I-0, I-0 1, I- 1, I- 19, I-2, I0, I0-02, I0 1, I0222.
