Book cataloging is to classify literature resources, compile catalogues and establish a collection catalogue system. The specific work content is: classify each kind of literature resources (such as books, CDs, tapes, newspapers, publications, etc.). ) According to certain standards (such as China Library Classification), give it a classification number (put a label on the book), and register records (now entered into the computer database, previously recorded on cards), such as title, author, publisher, time, classification number, etc.

Now it's all machine-readable catalogs, and it used to be manual.
