Most libraries require candidates to have a junior college or undergraduate degree when recruiting, because library work requires managers to know the content and form of each book, which is convenient for better management of books.

The work of a library usually includes the following aspects:

1. Editing: responsible for book purchasing and cataloging, including book selection, ordering, acceptance, registration, classification, cataloging and shelving.

2. Borrowing management: responsible for the registration and management of readers' borrowing and returning books, including handling library cards, borrowing and returning books.

3. Reference service: responsible for answering readers' inquiries and providing literature retrieval and information services, including helping readers find books and materials.

4. Service for readers: responsible for providing various services for readers, including reading guidance, reading promotion, reader activities, etc.

5. Resource management: responsible for the construction and management of library resources, including book purchasing, cataloging, shelving and maintenance.

6. Technical support: responsible for the maintenance and management of the library information system, including computer hardware, software and network.

To sum up, library work needs to have rich professional knowledge of library science, including basic knowledge of library classification, cataloging and retrieval. This knowledge needs to be mastered through systematic study and practice, so education is an important criterion to measure whether a person has this knowledge.
