For example:
h 3 14/66; i266/26( 10);
Where H3 14 I266 is the classification number. The classification number consists of classification code and number. 66 26( 10) is the number of species.
Second,
Book shelving method
The shelving method of books in our library: arrange the classification numbers first, and then compare them when the classification numbers are exactly the same.
1, classification and numbering method:
According to the order of classification code A~Z, the same books in classification code are arranged separately; For books with the same classification code, the principle of bit-by-bit comparison should be adopted when comparing the digital parts. That is, when the first digits are the same, compare the second digits; When the second place is the same, compare the third place; And so on.
Such as: TP1/kloc-0 /→ TP112→ TP131→ TP1→ tp2.
2. Species number arrangement: the comparison number arrangement adopts the principle of natural number arrangement.
For example: TP11→ TP11/2 → TP1/3 → TP1. H310.1/0001The classification number is one more than the previous one, and it ranks behind.
3. Special shelving rules: the special symbol appearing in the category number: "=" is the distinguishing code of different versions of the same book; "()" is the distinguishing code of different works by the same author; "-"is the code that distinguishes different authors. The order of special symbols in species number is: "= "→" () "→ "-"
Such as: h 319.4/5 → h 319.4/5 = 2 → h 319.4/5 (2) → h 319.4/5 (3) → h 3/kloc-.
