The capital letter at the beginning of the call number indicates the book classification number of the library (the category of books on the shelf will be marked at both ends of each shelf, for example, C stands for China ancient literature works, etc. ), the number behind should be the year of publication of the book or the number in this kind of book.
The telephone number is very continuous. Generally, the books on the shelves are arranged in the order of call numbers, so it is easier for readers to find the corresponding books by checking the call numbers before borrowing books.

Classification of calling numbers:
It mainly includes four types: classification/author word call number, classification/title call number, classification/time order call number and classification/book cataloging order call number.
Their structures are basically the same, and they are composed of two basic parts. One is the classification number, which is listed on the top line; The other part is the book number, that is, the author number, book name, publication year number and cataloging sequence number of such books, which are listed in the next line of the classification number. For a few books, the call number only consists of the above two basic parts. But for most books, in order to make the call number specific, the following symbols must be attached according to the specific situation:
(1) Append the title of the book, only after the author number, to distinguish different works of the same author in the same category.
(2) Version number, which is added to the next line of the author number or title to distinguish different versions of the same work.
(3) Add the book number or department number to the next line of the four numbers, such as the author number, to distinguish different volumes of multi-volume books and different volumes of the same book.
In addition, if necessary, the language number (used to distinguish foreign documents), document type identifier (such as reference book identifier) or special collection number should be appended after the classification number. The order of call numbers adopted by most libraries in China is classification/author and classification/book cataloging.
